ADVANCED LEGAL RESEARCH DISSERTATION
A Discussion of the Legal Implications of Autonomous Vehicles
Daniel Thompson
2
Abstract
An autonomous or ‘self-driving’ car is a vehicle capable of sensing its environment and navigating
without human input. A number of companies are researching this technology and it is expected to
mature in the next decade or so. Many jurisdictions around the world have started passing
legislation to address this new technology and integrate it into modern transport systems. Australia
needs to consider these different attempts and model its own legislative framework accordingly.
Issues such as liability law, drink driving legislation, driver licensing and other factors also need to
be taken into account.
In the longer term, the prospect arises that autonomous vehicles may come to not just complement,
but almost entirely succeed, manually-driven vehicles. Legal systems will have to consider the
question of whether human drivers, due to questions of safety and efficiency, should retain a ‘right
to drive’ or whether this right even exists. This paper will seek to outline these issues and chart a
possible course forward.

I INTRODUCTION
While examining a topic such as automated vehicles may sound more like a scientific dissertation, it
must be remembered that technology and the law are intimately linked. For some historical
examples, after the first manned hot air balloon flight took place in Paris in 1783, it was barely six
months before a local ordinance was passed banning their use without a permit.1It was also only
nineteen years after the invention of the first automobile that the United Kingdom passed its Motor
Car Act 1903 requiring every car to be registered and every driver licensed2. It is clear that every
new invention, from cars and planes to firearms and computers, is eventually ensnared in a fresh
web of legislation.
Jurisdictions worldwide are now grappling with the emerging technology of automated vehicles.
This is a field which promises to dramatically transform our society in the coming decades, with
major impacts not just on our transportation systems, but on our economy and legal systems as well.
It is also just a smaller part of the emerging field of artificial intelligence, which may come to
revolutionise nearly every aspect of our lives.
Currents predictions are that autonomous vehicles will start to become commercially viable and
widely used from 2020 onwards. In the long run, one may also make the prediction that by the year
2050 or thereabouts, autonomous vehicles will come to almost entirely supplant human drivers. A
number of jurisdictions may then start to pass restrictions on the freedom of movement of the latter
due to safety concerns and the uniquely greater efficiency of autonomous systems.

II NATURE OF THE TECHNOLOGY
An autonomous or ‘self-driving’ car is a vehicle capable of sensing its environment and navigating
without human input.3 While prototypes of such cars have existed for decades, it is only in the last
five years that serious moves have been made towards regulating and commercialising this
technology. Some companies, such as Tesla and Google, have received a great deal of publicity for
their work on self-driving vehicles. However, as of April 2016, at least thirty different companies,
most of them major automobile manufacturers, are believed to be exploring the technology.4
Autonomous vehicles are typically fitted with a number of different sensor systems including
cameras, radar and lasers. This allows them to sense the world around them and, through the use of
exhaustively tested software, successfully navigate and avoid collisions with obstacles, pedestrians
and other vehicles.
Many current or planned models are an extension of existing automated systems such as cruise
control, traction control or anti-lock braking. As of March 2016, Google alone has 54 autonomous
vehicles conducting street testing in California, Texas and Washington State. Collectively, they have
completed 1.5 million autonomous miles in seven years. As of July 2015, these cars had been
involved in 14 minor accidents, all of which were found to be the fault of the other party. More than
half of these collisions were cases of the Google car being ‘rear-ended’ by another vehicle.
The usual cause for this has been the Google car’s driving style being, apparently, too perfect. The
vehicles will rigorously obey the law, including completely stopping at traffic lights and stop signs,

something human drivers often fail to do. The first possible exception to this trend only occurred in
February 2016, when a Google car swerved to avoid sandbags on the road and struck the side of a
bus – an incident Google admitted was partly its fault. 5
As cases such as this demonstrate, numerous kinks must still be worked out regarding the
technology. While the latest models have become adept at navigating city streets, avoiding other
vehicles and obeying street signs, there are still difficulties with, for instance, identifying potholes,
predicting the movements of pedestrians and determining whether a piece of debris on the road is
substantial enough to warrant swerving around. Google cars are also yet to be tested in snow or
inclement weather due to safety concerns. Several companies have announced that the first truly
autonomous vehicles, ones where a human would be a mere passenger at all times, should be
commercially available by the year 2020, legal issues permitting.6

The first assumption about automated vehicles is that they are not presently legal. However, as
historical examples have shown, the law is typically neutral on new inventions until specific
legislation is passed to ban or regulate them. The wording of existing legislation may or may not
prohibit their use – for instance, if it requires a driver to be in control of a vehicle at all times.
Perhaps the real question to be answered is – by operating an autonomous vehicle, will a police
officer be able to stop you and charge you with an offence of some kind? Jurisdictions can currently
be divided into four categories:
1. No legislation has been passed, but operating an autonomous vehicle is probably illegal;
2. No legislation has been passed, but operating an autonomous vehicle is probably legal;
3. Legislation has been passed allowing testing under specific circumstances; and
4. Legislation has been passed allowing their general operation.
It should be noted that as of 2016, no autonomous cars are available for commercial sale. This
means the fourth category above is currently just restricted to prototypes, but is presumably ready
for the introduction of autonomous vehicles.
A America
As of 2016, legislation concerning autonomous vehicles has been passed in four US states. These
include Nevada (2011), California (2012), Florida (2012) and Michigan (2013) as well as the
District of Columbia (2013). Similar legislation is under consideration in a number of states.7
Nevada is a legislative pioneer in the field, having leapfrogged into the fourth category back in
2011. The Nevada law allows the operation of autonomous vehicles, though they must possess a

specific type of license and registration, including their own unique red number plates, and must
carry proof of insurance. 8
The California legislation permits autonomous vehicles to be operated or tested on the public roads
pending the adoption of safety standards and performance requirements.9 As of 2016, these are still
in development, meaning the state is still in category two, but aiming towards four.10
Florida first passed a law in 2012 allowing autonomous vehicles to be driven under strict
conditions, including a person needing to be expressly authorised by the state and requiring an
instrument of insurance.11 A new bill in 2016 loosened these requirements, with any individual
with a driver’s license now able to operate an autonomous vehicle.12 This moves the state from
category 3 to 4. Michigan’s law expressly permits testing of automated vehicles by certain parties
under certain conditions, keeping them in category 3.13
In the rest of the United States, the legal situation is less clear. Similar pieces of legislation are
being considered in a number of other states. Of those who have not yet considered the issue, the
reactions of the police or other agencies to autonomous vehicles may differ. A local police force
may conceivably crack down on autonomous vehicles by citing reckless driving statutes for
instance, or by refusing to register such cars in the first place. New York State has a law requiring a

driver to keep one hand on the wheel at all times14 (likely putting it in category 1), which could
clearly be relevant to users of autonomous vehicles. However, there do not appear to have been any
recent cases of drivers being arrested for piloting an autonomous vehicle, placing the rest of the
United States into category 2.
Shortly before the passage of California’s law, there was controversy over a Google test where a
legally blind driver made use of an autonomous vehicle. This case was supervised by the local
police. However, the California Highway Patrol cautioned that ‘in order to legally drive a vehicle in
California, it must be done so by an appropriately licensed driver’. This is true ‘whether the input
from a driver into the driving of a vehicle is done manually or electronically through entered
commands’.15 While no case went before the courts, police opinion was that an unlicensed driver
in an autonomous car could still be cited. Nevada’s law also prohibits a driver under the influence of
alcohol to control an autonomous vehicle.16
Given the legal uncertainty and differing laws, this patchwork approach may delay the long term
adoption of autonomous vehicles. Partially, it appears to be a quirk of the American legislative
hierarchy. Until this point in time the federal government has determined the technology, which
goes into cars – such as airbags and seat belts, while the individual states decide their own traffic
regulations. An autonomous vehicle blurs these distinctions with both hardware and software that
controls how the car drives. When it is not even clear who should be writing the rules, the quality
and uniformity of the relevant legislation is bound to be poor.

Article 8 of the 1968 Vienna Convention on Road Traffic states that ‘every driver shall at all times
be able to control his vehicle or to guide his animals’, presumably putting signatory states in the
first category.17 In 2014, however, an amendment was passed to the convention by the U.N.
Working Party on Road Traffic Safety.18 The new wording allows a car to drive itself, as long as
the system 'can be overridden or switched off by the driver'. A driver must also be present and able
to take the wheel at any time.19
While a huge step forward, this legislation was still limiting of truly autonomous vehicles. Google’s
latest self-driving cars do not even possess a steering wheel, meaning they could run afoul of local
road rules in the 74 countries that have signed the convention, including most of Europe and such
major countries as Russia and Brazil.
This situation began to be remedied in early 2016, when the transport ministers of all 28 European
Union member states met to sign the Declaration of Amsterdam in which the signatories pledged to
draw up rules and regulations to allow autonomous vehicles to be used on the roads.20 This takes
the legislative process forward. Rather than just repealing prior wording that appeared to ban
autonomous vehicles this takes the next step of beginning to form a legislative framework for their
use, aiming towards categories three or four.

One objective of the declaration is for the member states to work towards a ‘coherent European
framework for the deployment of interoperable connected and automated driving’.21 The goal is
that this framework is in place by 2019. Crucially, by adopting a ‘top-down’ approach, the member
states of the EU seek to avoid the situation that is starting to emerge in America, with a patchwork
of different and sometimes contradictory local laws.
As a sign of times to come, a recent experiment in April 2016 saw several convoys of autonomous
trucks, departing from locations as far away as Sweden and southern Germany and making their
way to the Dutch port of Rotterdam. This was the first cross-border experiment of its kind in
Europe.22
C Asia
As of 2015, twenty-four million cars were made in China, or nearly 30% of the world’s total,
making it by far the world’s largest manufacturer.23 Although car ownership remains low (with
only one car per eight people) it already has more cars on the road than any country except the
United States. Since 1984, more than 123,000km of expressways have been built across the country,
now totalling twice the length of America’s interstate highway system.24 This puts China roughly
on par with Europe or America as a centre of the world’s automobile market.

Like Europe, China has made recent moves to regulate autonomous vehicles using a top-down
approach. In 2016, the country’s Ministry of Industry and Information Technology announced plans
for draft legislation to accommodate self-driving cars as early as this year.25 This calls for
autonomous vehicles on highways within 3-5 years and, in an urban environment, by 2025. Until
then, China appears to be in the second category.
A number of companies have already tested or announced upcoming tests of autonomous vehicles
in China.26 Baidu (the ‘Chinese Google’) recently signed an agreement with the city of Wuhu in
eastern China, granting them permission to test autonomous vehicles on public roads over the next
five years (reminiscent of California’s 2012 legislation). Meanwhile, Volvo (bought by Chinese
manufacturer Geely Auto in 2010) recently announced plans to test 100 autonomous cars in China
(though details are yet to be decided). Just recently in April 2016, mirroring events in Europe, two
autonomous cars from Chang’an Automobiles completed a 2,000km trip from Chongqing to
Beijing. The company has the stated goal of selling such cars commercially as soon as 2020, in line
with American and European manufacturers.27

As of 2016, South Australia is the first Australian state to pass legislation with regards to
autonomous vehicles with the passage of its Motor Vehicles (Trials of Automotive Technologies)

Amendment Bill 2015.28 The bill allows the state’s Transport Minister to authorise specific trials of
automotive technology with the wording:
134D—Minister may authorise trials ofautomotive technologies
(1) The Minister may, by notice in the Gazette (an authorisation notice), authorise a specified person
to undertake a trial of automotive technology in accordance with this Part.
(2) Before authorising a trial under this Part,the Minister must—
(a) be satisfied that the person has in place, or will have in place before the trial commences,
arrangements for public liability insurance that comply with any requirements under section
134H29.
The insurance requirements are:
134H—Requirement for insurance
Aperson authorised to undertake an authorised trial must ensure that there is in force at all times
during the authorised trial period—
(a) a policy of public liability insurance indemnifying the owner and any authorised driver or
operator of the vehicle in an amount not less than the amount specified by the Minister in relation to
the trial in relation to death or bodily injury caused by, or arising out of, the use of the vehicle on a
road; and
(b) a policy of public liability insurance indemnifying the owner and any authorised driver or
operator of the vehicle in an amount not less than the amount specified by the Minister in relation to
28 Motor Vehicles (Trials of Automotive Technologies) Amendment Bill 2015 (SA).
29 Ibid 134D.
13
the trial in relation to damage to property caused by, or arising out of, the use of the vehicle on a
road; and
(c) any other policy of insurance that the Minister may reasonably require in relation to the trial.30
To deal with the issue of autonomous vehicles contravening other pieces of legislation, the Act
allows the transport minister to grant exemptions for specific trials:
134E—Exemptions from this and other Acts
(1) Subject to this section, the Minister may, for a purpose related to an authorised trial, exempt a
person or class of persons, or a vehicle or class of vehicles, from the operation of a provision or
provisions of this or any other Act, law or standard.31
These exemptions can be revoked. The act creates a penalty for a person who fails to abide by the
conditions of such an exemption, with the maximum penalty being a fine of $2500. Any person who
interferes with an authorised trial may also be subject to a penalty of $10 000.
This legislation only allows for specific trials, rather than the general operation of autonomous
vehicles, putting South Australia in category three. A person who drives an autonomous vehicle
without specific permission by the transport minister in South Australia may incur a fine of $2500.
This is approximately twice the fine for speeding by more than 45km/h (the maximum category)32
and seems a reasonable deterrent to unauthorised tests. It is most comparable to Michigan’s current
legislation or Florida’s 2012 law. Both this and the insurance requirements seem very prudent steps.

IV ROADMAPFOR AUSTRALIA
South Australia’s legislation is a good first step, permitting testing with express permission and
fining those who neglect to do so. An obvious problem is that, by adopting laws at the state level,
Australia threatens to go down the path of the United States with a patchwork of local laws. While
Australia has only six states, as opposed to fifty in the US or the twenty-eight members of the
European Union, a top-down approach is still preferable.
Like the United States, Australia faces the problem that there is no constitutional federal power over
road rules, allowing the states to adopt their own. Historically, road rules did differ in Australia,
until they were largely standardised in 1999 by agreement between the federal and state
governments with the adoption of the Australian Road Rules. As part of this agreement, the
National Transport Commission was created to regulate and ferment cooperation between the
different states and territories. Reviews of the Commission’s role are conducted every six years. The
2015 review makes only one mention of autonomous vehicles, describing them as a ‘priority for
future work’.33 Given the speed at which the technology is moving, it may be prudent for the
commission to consider the issue immediately, and have the states and territories adopt matching
legislation before 2020, when autonomous vehicles are expected to enter the market.
The best model for this legislation could be Nevada’s 2011 law. An autonomous vehicle should first
be defined, with language to the effect of –
33 National Transport Commission Review Expert Panel, 2015 Review of the National Transport
Commission: Report to the Transport and Infrastructure Council (2015)
<https://infrastructure.gov.au/transport/australia/ntc/reviews.aspx>.
15
An autonomous vehicle is a motor vehicle capable of sensing its environment and navigating
without human input.
The legislation could then instruct the state transport departments (referred to as ‘the department’)
to adopt guidelines for the introduction of autonomous vehicles, with wording similar to the Nevada
legislation:
The Department shall adopt regulations authorizing the operation of autonomous vehicles on roads
and road-related areas. The regulations required to be adopted must:
(a) Set forth requirements that an autonomous vehicle must meet before it may be operated on a
road or road-related area within this State;
(b) Set forth requirements for the insurance that is required to test or operate an autonomous
vehicle on road or road-related area within this State;
(c) Establish minimum safety standards for autonomous vehicles and their operation;
(d) Provide for the testing of autonomous vehicles;
(e) Set forth such other requirements as the Department determines to be necessary.
Like the Australian Road Rules this legislation should be as close to uniform as possible between
the states, but ultimately the state transport departments must approve of their own regulations.
Autonomous vehicles should be immediately identifiable both to other road users and law
enforcement officers. For this purpose, they should be issued with a special numberplate of a
different colour to regular cars. Autonomous vehicles should require insurance on the understanding
that the designer of the technology is liable for any accidents where the vehicle is found to be at
fault. Unlike the Nevada law, special licenses to pilot an autonomous vehicle may not be necessary
as an ordinary driver’s license should suffice.
16
While it may not have yet occurred with autonomous vehicles, some jurisdictions impose differing
speed limits on different categories of drivers. For instance, New South Wales’ law requires learner
drivers not to exceed an 80km/h speed limit.34 This is inadvisable. Not only would it lead to traffic
bottlenecks, all indications so far are that autonomous vehicles have most difficulty navigating
through dense urban environments at low speeds. Highways are one of the areas where they have
been most successful.35
Given that our road system already has to share its road passages, at times, with pedestrians,
cyclists, horse-drawn carts, heavy vehicles and other forms of transport, adding autonomous
vehicles into this mix, while presenting its own difficulties, should not prove logistically
impossible. Other obstacles come in the form of legal rights and public opinion.
V OTHER LEGAL ISSUES
A Use of electronic devices
With regards to law enforcement, questions arise as to how to quickly visually identify autonomous
against regular vehicles, for instance, with regards to the use of mobile phones and other electronic
devices while sitting in such a vehicle. Nevada in 2011 adopted legislation to add another category
to the list of exceptions for using a handheld device (such as a mobile phone) while in a vehicle:
For the purposes of this section, a person shall be deemed not to be operating a motor vehicle if the
motor vehicle is driven autonomously through the use of artificial-intelligence software and the
34 Road Rules 2014 (NSW) reg 24-1.

the-urban-jungle/>.
17
autonomous operation of the motor vehicle is authorised by law.36
Florida passed a similar law in 201337. Australia could adopt the same.
B Liability Law
Currently, great uncertainty surrounds autonomous vehicles and liability law. If such a vehicle
causes an accident, who is at fault, the driver, car manufacturer or designer of the autonomous
systems?
In 2015, Volvo announced they would accept liability for any crashes caused by their vehicles, but,
in many jurisdictions, the law remains unclear.38 Legislation passed in Nevada, Michigan, Florida
and Washington DC limits the liability of a car manufacturer whose vehicles have been modified to
drive autonomously.39 The basic rule appears to be that if a vehicle is at fault in an accident
because of a flaw in the autonomous technology, the designer of that technology will be liable,
rather than the driver or the maker of the unmodified car. Precedents also exist for other
autonomous systems. A 2009 train crash caused by a malfunction of the train’s automatic train-
control system led to 21 lawsuits and 84 out-of-court claims. 40
Australia should follow this obvious precedent. Manufacturers are unlikely to design, build and

market a new type of car if there is a chance they will all need be recalled after the first accident.
Autonomous vehicles also bring complex moral equations into play. In one scenario, if an automatic
vehicle faces a choice between hitting a little girl who has just run out onto the road, or veering off
the side, possibly killing the passengers, how should it decide? What if it later emerges that the
software was incorrect and the little girl was in fact a large dog? Strict ethical programming may
have to be implemented by law before autonomous vehicles become widespread.41
C Drink-Driving Laws
A possible use of autonomous cars is to reduce cases of driving under the influence of alcohol by
transporting people home as passengers instead. As of 2012, 24% of drivers killed on Victoria’s
roads had a blood alcohol concentration over 0.05 (by comparison, on average 0.3% of driver’s
tested are above the limit).42 At present, Nevada’s 2011 law prohibits an inebriated driver from
taking the wheel of an autonomous vehicle, and it appears no jurisdiction worldwide currently
allows a drunk ‘driver’ to make use of one.43 This presents a curious contradiction, in that
jurisdictions are permitting texting and even legally blind drivers to pilot automatic cars, but not
inebriated ones.
However, for the time being, it may be best to keep this precedent. No current car can be considered
100% autonomous. Even Google has not yet tested its cars in inclement weather or snow due to

Zealand Institute of Insurance and Finance 1.

safety/statistics/summaries/drink-driving-statistics>.

19
safety concerns. If the autonomous vehicle encounters an obstacle it cannot navigate, the driver is
still expected to take control. It should therefore not be legal for a driver to be intoxicated if in
control of a vehicle, even if it is at that moment driving autonomously.
This area, however, should be subject to regular review. If, in the next ten years or so, completely
autonomous vehicles emerge, delegating the ‘driver’ purely to the role of ‘passenger’ then the law
might be changed. A distinction could be made between vehicles with or without a steering wheel
for instance. In the United States, the National Highway Traffic Safety Administration (NHTSA)
has proposed a formal five-stage classification system regarding autonomous vehicles of which only
the final category is completely autonomous.44 Laws could certainly differ based on whether a
vehicle is partially or completely automated.
VI REDUCTION IN THE ROAD TOLL
Reduction of the road toll is surely the greatest single argument in favour of autonomous vehicles,
and explains the billions of dollars invested in research in recent decades. Globally, 1.3 million
people currently die in automobile accidents every year, with another 50 million injured. Current
trends are that middle and low-income countries will see an increase in traffic deaths of 83 percent
by 2020 against 2000 figures, while for Europe and other high-income countries, that figure will
decrease by 27 percent over the same period.45

certain number of collisions would seem to be inevitable. For instance, a tree falling in front of a
speeding car which has no chance to brake. However, at least 90% of accidents are attributable to
human error,46 something that autonomous vehicles may entirely eliminate.
VII FUTURE TRANSPORTATION SYSTEMS
Autonomous vehicles are expected to change our transportation system in a number of ways. The
impact will be more than simply ‘cars driving themselves’ and avoiding routine accidents. Various
techniques become possible in a system made up partly or completely of autonomous vehicles.
A Vehicle Platooning
Due to quicker reaction times, autonomous vehicles could be positioned much closer together on
the road. Human drivers must typically stay two or three seconds travel time behind the car in front
in order to maintain a safe braking distance. On highways, this can mean a gap of 50-100 meters.
Recent trials have demonstrated that autonomous road trains could travel with gaps no bigger than 6
meters between the vehicles. By travelling more closely together, wind resistance and with it fuel
costs would be significantly decreased, as well as overall congestion.47
B Higher Speed Limits
Speed limits have slowly increased over the course of the 20th century. The United States had a
46 Ibid.
47 E Larsson, G Sennton and J Larson, ‘The Vehicle Platooning Problem: Computational Complexity and
Heuristics’ (2015) 60 Transportation Research 258.
21
federal mandated speed limit of 55mph (90km/h) until 1987 and 65mph (105km/h) until 1995
before abolishing it entirely. Most individual American states now have limits between 70 and
80mph (110-130km/h).48 Aside from a few exceptions (such as the German autobahns), most
countries are also in this range. This results in something of a contradiction, as most modern cars
are capable of speeds well in excess of 200km/h.
The two main restraints on speed limits are fuel efficiency and driver reaction times. However, it so
happens that the advent of autonomous vehicles is coinciding with the introduction of electric cars.
These cars promise considerably reduced energy costs, potentially removing both obstacles at once.
A road system dominated by autonomous electric cars could see speed limits increased considerably
to as much as 200km/h. The concept of speed limits could even be eliminated entirely in favour or
simply requiring autonomous vehicles to decide on their own safe speed, as drivers are required on
German autobahns.
C Obsolescence of Traffic Lights and Other Traffic Regulators
A major change in the road system could come about due to the obsolescence of traffic lights in a
road system run solely on automated vehicles. Traffic lights (or else alternatives like ‘stop’ signs or
round-a-bouts) are currently necessary at intersections to regulate traffic and prevent collisions. In a
system comprising solely of self-driving cars, this may not be necessary due to a combination of
inhumanly quick reaction times and instantaneous communications between them.
If two self-driving cars are both approaching an intersection at high speeds, on course for a

March 2015) <http://brilliantmaps.com/speed-limits/>.
22
collision, it is not necessarily the case that one of the cars must stop entirely to allow the other to
pass, as it would with two human drivers. Based on a simple communication between the vehicles,
one could ‘agree’ to either speed up or (more likely) slow down as they approached the intersection.
At a speed of 100km/h, a difference of less than a fifth of a second means the second car would
miss the first by just over five meters – enough that the two would not collide. Such a ‘slot-based
system’ is obviously impractical for human drivers. It could only be used in an intersection where
only autonomous vehicles were permitted. This would decrease both travel times and road
congestion.49 An issue does arise however, with integrating such a system with pedestrians, cyclists
and other road users. Regulation 81 of the Australian Road Rules states:
81—Giving way at a pedestrian crossing
(1) Adriver approaching a pedestrian crossing must drive at a speed at which the driver
can, if necessary,stop safely before the crossing.50
This would appear to contradict the practice a slot-based intersection. However, it may still be
compatible with Pedestrian Light Controlled (or ‘Pelican’) Crossings – equipped in Australia with
the ‘little green man’ and ‘little red man’. Traffic would move seamlessly until a pedestrian pressed
a button, at which point all the autonomous vehicles nearby would be ordered to stop.
In addition to the above, a system composed solely of autonomous vehicles could see narrower
lanes and reduced space required for parking.51 It could reduce significantly the 42 hours an
average commuter in America spends stuck in traffic jams each year.52 Car-sharing could become

VIII THE FATE OF HUMAN DRIVERS
The combination of all the above factors makes it likely – if not inevitable, that humans will
eventually be considered an unacceptable liability on our roads.54 The American Institute of
Electrical and Electronics Engineers (IEEE) recently released predictions that autonomous cars will
account for up to 75% of vehicles on the road by the year 2040.55
By perhaps 2050, there should be little obstacle, other than human error, to a road system with
routine platooning of vehicles, ride-sharing, highway speed limits raised closer to 200km/h and
many intersections integrated into a slot-based system without any traffic lights or other traffic
regulators. Given these vast improvements in speed and efficiency, it will become harder and harder
to justify the presence of human drivers.
Perhaps starting with highways, and then spreading to the rest of the road system, human drivers are
likely to face restrictions on their movement from about the middle of this century. Such regulation
of our road system is hardly unprecedented. Already, upon entering a freeway in Australia, it is
common to see signs with wording to the effect of ‘Start Freeway: No Pedestrians: Animals:
Agricultural Machinery: Beyond This Point’ or ‘No Cyclists Permitted on this Freeway’. It is
conceivable that similar signs could be installed within the next fifty years, with wording to the
effect of ‘Autonomous Vehicles Only Beyond This Point.’ The detection of an independently driven
vehicle would alert nearby vehicles to its presence, and perhaps cause a reduction in their speed.
The police could then be dispatched to apprehend the offending driver. Sanctions such as a fine or
loss of license could follow, much the same as under today’s road rules.

55 Bunghez, above n 3.

A Legal Obstacles in Australia
While it may make sense on purely safety grounds, the banning of human drivers may run up
against an individual’s legal right to freedom of movement. This is a basic freedom originating in
common law and also enshrined in s 92 of the Australian Constitution,56 stating:
On the imposition of uniform duties of customs, trade,commerce, and intercourse among the States,
whether by means of internal carriage or ocean navigation, shall be absolutely free.
A number of cases have dealt with the precise meaning of this section. A distinction has been found
between ‘trade and commerce’ and ‘intercourse’. Case law indicates that ‘trade and commerce’
includes such acts as ‘the mutual communings, the negotiations, verbal and by correspondence, the
bargain, the transport and the delivery’.57
Intercourse, meanwhile, has a broader definition. In Gratwick v Johnson58, Starke J said that the
people of Australia ‘are thus free to pass to and from among the states without burden, hindrance or
restriction’. However, in Cole v Whitfield59 , the High Court indicated this does not mean that
‘every form of intercourse must be left without any restriction or regulation in order to satisfy the
guarantee of freedom’. Mason CJ in Cunliffe v Commonwealth60 also said that the freedom of
intercourse which s 92 guarantees is not absolute. Any law which ‘imposes a burden or restriction’

on movement across a border would be invalid unless it was ‘reasonably necessary’ and the burden
or restriction was not disproportionate to that end. It would be a matter of weighing the competing
public interests. Given that 1,500 deaths a year are caused by vehicle accidents, it is readily
foreseeable the High Court would consider this a ‘competing public interest’.
If instead the High Court followed the earlier precedent in Gratwick,61 and decided that s 92
created a general freedom of movement, this may prevent autonomous vehicles completely
replacing human drivers without a constitutional referendum on the issue. Indeed, it may be
advisable for such a monumental change to be accompanied by a referendum regardless. Given
current technological trends, such an event may occur in a timeframe of around 2050-2060.
Regardless, it is easy to conceive of drivers making legal challenges to a law banning human drivers
from certain stretches of road.
B Other Jurisdictions
Whether humans are effectively banned from driving, at least on certain stretches of road, may
depend on the relevant constitutional rights and weight of public opinion in the jurisdiction in
question. As we have seen, the Australian Constitution has uncertain wording on the issue. A
jurisdiction like the United Kingdom has no constitution, however, it could call upon the common
law or legislation, such as the Magna Carta62 or the English Bill of Rights.63 Indeed, art 13 of the
Universal Declaration of Human Rights reads:
61 Gratwick v Johnson (1945) 70 CLR 1.
62 Magna Carta 1297 (Eng) 25 Edw 1, c 42.
63 Bill of Rights 1688 (Eng) 1 Wm & M sess 2, c 2.
27
(1) Everyone has the right to freedom of movement and residence within the borders of each
State.64
In any country, which has signed the declaration, it could perhaps be used to mount legal challenges
to any laws restricting the movement of human drivers.
While not dealing specifically with autonomous vehicles, a number of cases have challenged other
pieces of legislation restricting people’s freedom of movement. Of particular relevance would be a
2011 case from the American state of Kentucky. Eight men, belonging to the local Amish
community, were charged for failing to abide by a recently passed law requiring them to display
bright orange triangles on the back of their horse buggies. This was passed after a string of recent
crashes between buggies and other vehicles.65 As the display of these bright symbols went against
their religion, the Amish refused and were subsequently fined and, after refusing to pay the fines,
sentenced to short terms of imprisonment.66 In 2012, the Supreme Court of Kentucky upheld the
convictions,67 however, the state legislature also changed the law, allowing other alternatives to the
orange triangles to be used.68
It is easy to see similar cases occurring, perhaps in another thirty or forty years, regarding manually
piloted vehicles. Also noteworthy is the way the criminal convictions, along with subsequent public
support (the men concerned were represented by the American Civil Liberties Union) compelled a

change in the law. The Amish population in North America is just 250 000 – less than 0.1% of the
general population69 and it appears only a minority have objections to displaying any required
symbols.
More than any other factor, the weight of public opinion could delay laws to prevent humans from
driving. Drivers currently make up the vast majority of the population. Another group worth
considering are motorcyclists. As of 2015, of the 18 million vehicles on Australia’s roads, more than
800,000 are motorcycles, or 4.5% of the total70. At present, there does not appear to be any
foreseeable way by which a motorcycle can become self-driving (given that the rider must
mechanically move the handlebars and use his legs to steady the bike when stationary). If human
drivers are to be banned from a stretch of road, presumably it will become off-limits to all cyclists
and motorcyclists as well. One counter-argument is that motorcyclists pose little risk to other road
users, given that in a collision, a motorcycle is less likely to cause great damage to a car or its
occupants. For this reason, they may be allowed to continue riding, solely at their own risk.
As a sign of things to come, the proportion of the population who have a license (in America at
least) has been declining since the 1980s. Regarding young people, 69% of 19 year olds had
licenses in 2014, compared to 87.3% in 1983.71 On the issue of banning human drivers, some
polling has already been conducted. A 2015 poll indicated that 27% of Americans – a surprisingly
large minority, would support restrictions on human drivers if autonomous vehicles were found to

be safer.72
IX CONCLUSION
Given current trends, autonomous vehicles as a technology are likely to mature in the next five to
ten years. Worldwide, there is widespread enthusiasm for their legalisation and many jurisdictions
are already laying the legislative groundwork for their use. Given current trends, in developed
countries at least, a steep decline in the road toll, perhaps close to 90%, can be expected in the
coming decades.
Australia should seek to adopt, as soon as possible, updated laws permitting the testing and eventual
commercial sale of autonomous vehicles in Australia. The Nevada and California legislation should
be looked at as precedents. While the individual states have to adopt their own legislation these
should be as uniform as possible in line with the Australian Road Rules.
Longer term, it is less clear that most jurisdictions will embrace the idea of a completely automated
transport system. Due to concerns with freedom of movement and a general enthusiasm for driving,
it may be a considerable while before completely autonomous systems become a reality, allowing
changes such as higher speed limits and the slot-based traffic systems described above.
Any country considering this should look at all the possible impacts, gauging public opinion as
widely as possible, before making such a revolutionary change. If this does come to pass, no doubt
legal challenges will emerge to any laws restricting the freedom of movement of human drivers. As
with many areas of law, the issue comes down to an ongoing balancing act between people’s
security and freedom.

The Legal Implications of Autonomous Vehicles

  • 1. 1 ADVANCED LEGAL RESEARCH DISSERTATION A Discussion of the Legal Implications of Autonomous Vehicles Daniel Thompson
  • 2. 2 Abstract An autonomous or ‘self-driving’ car is a vehicle capable of sensing its environment and navigating without human input. A number of companies are researching this technology and it is expected to mature in the next decade or so. Many jurisdictions around the world have started passing legislation to address this new technology and integrate it into modern transport systems. Australia needs to consider these different attempts and model its own legislative framework accordingly. Issues such as liability law, drink driving legislation, driver licensing and other factors also need to be taken into account. In the longer term, the prospect arises that autonomous vehicles may come to not just complement, but almost entirely succeed, manually-driven vehicles. Legal systems will have to consider the question of whether human drivers, due to questions of safety and efficiency, should retain a ‘right to drive’ or whether this right even exists. This paper will seek to outline these issues and chart a possible course forward.
  • 3. 3 I INTRODUCTION While examining a topic such as automated vehicles may sound more like a scientific dissertation, it must be remembered that technology and the law are intimately linked. For some historical examples, after the first manned hot air balloon flight took place in Paris in 1783, it was barely six months before a local ordinance was passed banning their use without a permit.1It was also only nineteen years after the invention of the first automobile that the United Kingdom passed its Motor Car Act 1903 requiring every car to be registered and every driver licensed2. It is clear that every new invention, from cars and planes to firearms and computers, is eventually ensnared in a fresh web of legislation. Jurisdictions worldwide are now grappling with the emerging technology of automated vehicles. This is a field which promises to dramatically transform our society in the coming decades, with major impacts not just on our transportation systems, but on our economy and legal systems as well. It is also just a smaller part of the emerging field of artificial intelligence, which may come to revolutionise nearly every aspect of our lives. Currents predictions are that autonomous vehicles will start to become commercially viable and widely used from 2020 onwards. In the long run, one may also make the prediction that by the year 2050 or thereabouts, autonomous vehicles will come to almost entirely supplant human drivers. A number of jurisdictions may then start to pass restrictions on the freedom of movement of the latter due to safety concerns and the uniquely greater efficiency of autonomous systems. 1 Peter H Sand, ‘An Historical Survey of International Air Law Before the Second World War’(1960-61) 7 McGill Law Journal 24,25. 2 Motor Car Act 1903 (UK).
  • 4. 4 II NATURE OF THE TECHNOLOGY An autonomous or ‘self-driving’ car is a vehicle capable of sensing its environment and navigating without human input.3 While prototypes of such cars have existed for decades, it is only in the last five years that serious moves have been made towards regulating and commercialising this technology. Some companies, such as Tesla and Google, have received a great deal of publicity for their work on self-driving vehicles. However, as of April 2016, at least thirty different companies, most of them major automobile manufacturers, are believed to be exploring the technology.4 Autonomous vehicles are typically fitted with a number of different sensor systems including cameras, radar and lasers. This allows them to sense the world around them and, through the use of exhaustively tested software, successfully navigate and avoid collisions with obstacles, pedestrians and other vehicles. Many current or planned models are an extension of existing automated systems such as cruise control, traction control or anti-lock braking. As of March 2016, Google alone has 54 autonomous vehicles conducting street testing in California, Texas and Washington State. Collectively, they have completed 1.5 million autonomous miles in seven years. As of July 2015, these cars had been involved in 14 minor accidents, all of which were found to be the fault of the other party. More than half of these collisions were cases of the Google car being ‘rear-ended’ by another vehicle. The usual cause for this has been the Google car’s driving style being, apparently, too perfect. The vehicles will rigorously obey the law, including completely stopping at traffic lights and stop signs, 3 Corina Larisa Bunghez, ‘The Future of Transportation: Autonomous Vehicles’ (2015) 5(5) International Journal of Economic Practices and Theories 447, 447. 4 Sam Shead, 30 Companies are now Making Self-Driving Cars that Could One Day be 'Deathproof'(22 April 2016) Business Insider Australia <http://www.businessinsider.com.au/30-companies-are-now-making- self-driving-cars-2016-4?r=UK&IR=T>.
  • 5. 5 something human drivers often fail to do. The first possible exception to this trend only occurred in February 2016, when a Google car swerved to avoid sandbags on the road and struck the side of a bus – an incident Google admitted was partly its fault. 5 As cases such as this demonstrate, numerous kinks must still be worked out regarding the technology. While the latest models have become adept at navigating city streets, avoiding other vehicles and obeying street signs, there are still difficulties with, for instance, identifying potholes, predicting the movements of pedestrians and determining whether a piece of debris on the road is substantial enough to warrant swerving around. Google cars are also yet to be tested in snow or inclement weather due to safety concerns. Several companies have announced that the first truly autonomous vehicles, ones where a human would be a mere passenger at all times, should be commercially available by the year 2020, legal issues permitting.6 III Current Legal Situation 5 Keith Naughton, Humans Are Slamming Into Driverless Cars and Exposing a Key Flaw (18 December 2015) Bloomberg Technology, <http://www.bloomberg.com/news/articles/2015-12-18/humans-are- slamming-into-driverless-cars-and-exposing-a-key-flaw>; Google Self-Driving CarProject: Monthly Report (March 2016) <https://static.googleusercontent.com/media/www.google.com/lt//selfdrivingcar/files/reports/report- 0316.pdf>; Mark Prigg, Can Self-Driving Cars Cope with Illogical Humans?

  • 6. 6 The first assumption about automated vehicles is that they are not presently legal. However, as historical examples have shown, the law is typically neutral on new inventions until specific legislation is passed to ban or regulate them. The wording of existing legislation may or may not prohibit their use – for instance, if it requires a driver to be in control of a vehicle at all times. Perhaps the real question to be answered is – by operating an autonomous vehicle, will a police officer be able to stop you and charge you with an offence of some kind? Jurisdictions can currently be divided into four categories: 1. No legislation has been passed, but operating an autonomous vehicle is probably illegal; 2. No legislation has been passed, but operating an autonomous vehicle is probably legal; 3. Legislation has been passed allowing testing under specific circumstances; and 4. Legislation has been passed allowing their general operation. It should be noted that as of 2016, no autonomous cars are available for commercial sale. This means the fourth category above is currently just restricted to prototypes, but is presumably ready for the introduction of autonomous vehicles. A America As of 2016, legislation concerning autonomous vehicles has been passed in four US states. These include Nevada (2011), California (2012), Florida (2012) and Michigan (2013) as well as the District of Columbia (2013). Similar legislation is under consideration in a number of states.7 Nevada is a legislative pioneer in the field, having leapfrogged into the fourth category back in 2011. The Nevada law allows the operation of autonomous vehicles, though they must possess a 7 Gabriel Weiner and Bryant Walker Smith, Automated Driving: Legislative and Regulatory Action (20 May 2016) Center for Internet and Society <cyberlaw.stanford.edu/wiki/index.php/Automated_Driving:_Legislative_and_Regulatory_Action>.
  • 7. 7 specific type of license and registration, including their own unique red number plates, and must carry proof of insurance. 8 The California legislation permits autonomous vehicles to be operated or tested on the public roads pending the adoption of safety standards and performance requirements.9 As of 2016, these are still in development, meaning the state is still in category two, but aiming towards four.10 Florida first passed a law in 2012 allowing autonomous vehicles to be driven under strict conditions, including a person needing to be expressly authorised by the state and requiring an instrument of insurance.11 A new bill in 2016 loosened these requirements, with any individual with a driver’s license now able to operate an autonomous vehicle.12 This moves the state from category 3 to 4. Michigan’s law expressly permits testing of automated vehicles by certain parties under certain conditions, keeping them in category 3.13 In the rest of the United States, the legal situation is less clear. Similar pieces of legislation are being considered in a number of other states. Of those who have not yet considered the issue, the reactions of the police or other agencies to autonomous vehicles may differ. A local police force may conceivably crack down on autonomous vehicles by citing reckless driving statutes for instance, or by refusing to register such cars in the first place. New York State has a law requiring a 8 Nev Rev Stat § 483. 9 CalVehicle Code § 16.6. 10 California Department of Motor Vehicles, Autonomous Vehicles in California <https://www.dmv.ca.gov/portal/dmv/detail/vr/autonomous/auto>. 11 National Conference of State Legislatures, Autonomous: Self-Driving VehiclesLegislation <http://www.ncsl.org/research/transportation/autonomous-vehicles-legislation.aspx>. 12 Fla Stat § 316. 13 Mich Comp Laws § 257.
  • 8. 8 driver to keep one hand on the wheel at all times14 (likely putting it in category 1), which could clearly be relevant to users of autonomous vehicles. However, there do not appear to have been any recent cases of drivers being arrested for piloting an autonomous vehicle, placing the rest of the United States into category 2. Shortly before the passage of California’s law, there was controversy over a Google test where a legally blind driver made use of an autonomous vehicle. This case was supervised by the local police. However, the California Highway Patrol cautioned that ‘in order to legally drive a vehicle in California, it must be done so by an appropriately licensed driver’. This is true ‘whether the input from a driver into the driving of a vehicle is done manually or electronically through entered commands’.15 While no case went before the courts, police opinion was that an unlicensed driver in an autonomous car could still be cited. Nevada’s law also prohibits a driver under the influence of alcohol to control an autonomous vehicle.16 Given the legal uncertainty and differing laws, this patchwork approach may delay the long term adoption of autonomous vehicles. Partially, it appears to be a quirk of the American legislative hierarchy. Until this point in time the federal government has determined the technology, which goes into cars – such as airbags and seat belts, while the individual states decide their own traffic regulations. An autonomous vehicle blurs these distinctions with both hardware and software that controls how the car drives. When it is not even clear who should be writing the rules, the quality and uniformity of the relevant legislation is bound to be poor. B Europe 14 NYVeh & Traf L § 33-1226 (2014). 15 Mark Hachman, Police: Blind Driver's Trip in Google's Self-Driving Car WasLegal (29 March 2012) PCMag <http://www.pcmag.com/article2/0,2817,2402380,00.asp>. 16 Nev Rev Stat § 483.
  • 9. 9 Article 8 of the 1968 Vienna Convention on Road Traffic states that ‘every driver shall at all times be able to control his vehicle or to guide his animals’, presumably putting signatory states in the first category.17 In 2014, however, an amendment was passed to the convention by the U.N. Working Party on Road Traffic Safety.18 The new wording allows a car to drive itself, as long as the system 'can be overridden or switched off by the driver'. A driver must also be present and able to take the wheel at any time.19 While a huge step forward, this legislation was still limiting of truly autonomous vehicles. Google’s latest self-driving cars do not even possess a steering wheel, meaning they could run afoul of local road rules in the 74 countries that have signed the convention, including most of Europe and such major countries as Russia and Brazil. This situation began to be remedied in early 2016, when the transport ministers of all 28 European Union member states met to sign the Declaration of Amsterdam in which the signatories pledged to draw up rules and regulations to allow autonomous vehicles to be used on the roads.20 This takes the legislative process forward. Rather than just repealing prior wording that appeared to ban autonomous vehicles this takes the next step of beginning to form a legislative framework for their use, aiming towards categories three or four. 17 Convention on Road Traffic, opened for signature on 8 November 1968, 1042 UNTS 1671 (entered into force 21 May 1977) arts 8-5. 18 Mark Prigg, Is Europe Set to Win the Race for Driverless Cars? New Treaty MeansAutomated Vehicles could be on EU Roads Far before the US Gives Go-Ahead (20 May 2014) Daily Mail Australia <http://www.dailymail.co.uk/sciencetech/article-2633237/Europe-set-win-race-driverless-cars- New-global-treaty-means-automated-vehicles-EU-roads-far-US-gives-ahead.html> 19 Economic and Social Council, Report of the Sixty-Eighth Session of the Working Party on Road Traffic Safety, ECE/TRANS/WP.1/145 (17 April 2014). 20 Declaration of Amsterdamon Cooperation in the Field of Connected and Automated Driving (14 April 2016) < http://english.eu2016.nl/binaries/eu2016-en/documents/publications/2016/04/14/declaration-of- amsterdam/2016-04-08-declaration-of-amsterdam-final-format-3.pdf>.
  • 10. 10 One objective of the declaration is for the member states to work towards a ‘coherent European framework for the deployment of interoperable connected and automated driving’.21 The goal is that this framework is in place by 2019. Crucially, by adopting a ‘top-down’ approach, the member states of the EU seek to avoid the situation that is starting to emerge in America, with a patchwork of different and sometimes contradictory local laws. As a sign of times to come, a recent experiment in April 2016 saw several convoys of autonomous trucks, departing from locations as far away as Sweden and southern Germany and making their way to the Dutch port of Rotterdam. This was the first cross-border experiment of its kind in Europe.22 C Asia As of 2015, twenty-four million cars were made in China, or nearly 30% of the world’s total, making it by far the world’s largest manufacturer.23 Although car ownership remains low (with only one car per eight people) it already has more cars on the road than any country except the United States. Since 1984, more than 123,000km of expressways have been built across the country, now totalling twice the length of America’s interstate highway system.24 This puts China roughly on par with Europe or America as a centre of the world’s automobile market. 21 Ibid. 22 Agence France-Presse, Convoy of Self-Driving Trucks CompletesFirst European Cross-Border Trip (7 April 2016) The Guardian <https://www.theguardian.com/technology/2016/apr/07/convoy-self-driving- trucks-completes-first-european-cross-border-trip>. 23 Organisation Internationale des Constructeurs d'Automobiles, World Motor Vehicle Production by Country and Type 2014-2015 <http://www.oica.net/category/production-statistics/>. 24 Ministry of Transport of the People’s Republic of China, 2014 Transportation Industry Statistical Bulletin (23 July 2015) <http://www.moc.gov.cn/zhuzhan/jiaotonggaikuang/201507/t20150723_1853384.html>.
  • 11. 11 Like Europe, China has made recent moves to regulate autonomous vehicles using a top-down approach. In 2016, the country’s Ministry of Industry and Information Technology announced plans for draft legislation to accommodate self-driving cars as early as this year.25 This calls for autonomous vehicles on highways within 3-5 years and, in an urban environment, by 2025. Until then, China appears to be in the second category. A number of companies have already tested or announced upcoming tests of autonomous vehicles in China.26 Baidu (the ‘Chinese Google’) recently signed an agreement with the city of Wuhu in eastern China, granting them permission to test autonomous vehicles on public roads over the next five years (reminiscent of California’s 2012 legislation). Meanwhile, Volvo (bought by Chinese manufacturer Geely Auto in 2010) recently announced plans to test 100 autonomous cars in China (though details are yet to be decided). Just recently in April 2016, mirroring events in Europe, two autonomous cars from Chang’an Automobiles completed a 2,000km trip from Chongqing to Beijing. The company has the stated goal of selling such cars commercially as soon as 2020, in line with American and European manufacturers.27 D Australia As of 2016, South Australia is the first Australian state to pass legislation with regards to autonomous vehicles with the passage of its Motor Vehicles (Trials of Automotive Technologies) 25 Jake Spring, Look Mao,No Hands!China’sRoadmap to Self-Driving Cars (22April 2016) Reuters <http://www.reuters.com/article/us-autoshow-beijing-china-selfdriving-idUSKCN0XK021>. 26 Alex Davies, Baidu’s Self-Driving Car Has Hit The Road (12 September 2015) <https://www.wired.com/2015/12/baidus-self-driving-car-has-hit-the-road/>. 27 Bloomberg News, Self-Driving Car Completes 1,200 Mile Road Trip AcrossChina (18April 2016) <http://www.bloomberg.com/news/articles/2016-04-18/china-s-changan-auto-completes-1-200-mile- autonomous-drive-test>.

(2) Before authorising a trial under this Part,the Minister must— (a) be satisfied that the person has in place, or will have in place before the trial commences, arrangements for public liability insurance that comply with any requirements under section 134H29. The insurance requirements are: 134H—Requirement for insurance Aperson authorised to undertake an authorised trial must ensure that there is in force at all times during the authorised trial period— (a) a policy of public liability insurance indemnifying the owner and any authorised driver or operator of the vehicle in an amount not less than the amount specified by the Minister in relation to the trial in relation to death or bodily injury caused by, or arising out of, the use of the vehicle on a road; and (b) a policy of public liability insurance indemnifying the owner and any authorised driver or operator of the vehicle in an amount not less than the amount specified by the Minister in relation to 28 Motor Vehicles (Trials of Automotive Technologies) Amendment Bill 2015 (SA). 29 Ibid 134D.

The act creates a penalty for a person who fails to abide by the conditions of such an exemption, with the maximum penalty being a fine of $2500. Any person who interferes with an authorised trial may also be subject to a penalty of $10 000. This legislation only allows for specific trials, rather than the general operation of autonomous vehicles, putting South Australia in category three. A person who drives an autonomous vehicle without specific permission by the transport minister in South Australia may incur a fine of $2500. This is approximately twice the fine for speeding by more than 45km/h (the maximum category)32 and seems a reasonable deterrent to unauthorised tests. It is most comparable to Michigan’s current legislation or Florida’s 2012 law. Both this and the insurance requirements seem very prudent steps. 30 Ibid 134H. 31 Ibid 134E. 32 Department of Planning, Transport and Infrastructure (SA), Road Rules: Offenses and Penalties <http://www.mylicence.sa.gov.au/road-rules/offences-and-penalties#summaryofoffences>.
  • 14. 14 IV ROADMAPFOR AUSTRALIA South Australia’s legislation is a good first step, permitting testing with express permission and fining those who neglect to do so. An obvious problem is that, by adopting laws at the state level, Australia threatens to go down the path of the United States with a patchwork of local laws. While Australia has only six states, as opposed to fifty in the US or the twenty-eight members of the European Union, a top-down approach is still preferable. Like the United States, Australia faces the problem that there is no constitutional federal power over road rules, allowing the states to adopt their own. Historically, road rules did differ in Australia, until they were largely standardised in 1999 by agreement between the federal and state governments with the adoption of the Australian Road Rules. As part of this agreement, the National Transport Commission was created to regulate and ferment cooperation between the different states and territories. Reviews of the Commission’s role are conducted every six years. The 2015 review makes only one mention of autonomous vehicles, describing them as a ‘priority for future work’.33 Given the speed at which the technology is moving, it may be prudent for the commission to consider the issue immediately, and have the states and territories adopt matching legislation before 2020, when autonomous vehicles are expected to enter the market. The best model for this legislation could be Nevada’s 2011 law. An autonomous vehicle should first be defined, with language to the effect of – 33 National Transport Commission Review Expert Panel, 2015 Review of the National Transport Commission: Report to the Transport and Infrastructure Council (2015) <https://infrastructure.gov.au/transport/australia/ntc/reviews.aspx>.
  • 15. 15 An autonomous vehicle is a motor vehicle capable of sensing its environment and navigating without human input. The legislation could then instruct the state transport departments (referred to as ‘the department’) to adopt guidelines for the introduction of autonomous vehicles, with wording similar to the Nevada legislation: The Department shall adopt regulations authorizing the operation of autonomous vehicles on roads and road-related areas. The regulations required to be adopted must: (a) Set forth requirements that an autonomous vehicle must meet before it may be operated on a road or road-related area within this State; (b) Set forth requirements for the insurance that is required to test or operate an autonomous vehicle on road or road-related area within this State; (c) Establish minimum safety standards for autonomous vehicles and their operation; (d) Provide for the testing of autonomous vehicles; (e) Set forth such other requirements as the Department determines to be necessary. Like the Australian Road Rules this legislation should be as close to uniform as possible between the states, but ultimately the state transport departments must approve of their own regulations. Autonomous vehicles should be immediately identifiable both to other road users and law enforcement officers. For this purpose, they should be issued with a special numberplate of a different colour to regular cars. Autonomous vehicles should require insurance on the understanding that the designer of the technology is liable for any accidents where the vehicle is found to be at fault. Unlike the Nevada law, special licenses to pilot an autonomous vehicle may not be necessary as an ordinary driver’s license should suffice.
  • 16. 16 While it may not have yet occurred with autonomous vehicles, some jurisdictions impose differing speed limits on different categories of drivers. For instance, New South Wales’ law requires learner drivers not to exceed an 80km/h speed limit.34 This is inadvisable. Not only would it lead to traffic bottlenecks, all indications so far are that autonomous vehicles have most difficulty navigating through dense urban environments at low speeds. Highways are one of the areas where they have been most successful.35 Given that our road system already has to share its road passages, at times, with pedestrians, cyclists, horse-drawn carts, heavy vehicles and other forms of transport, adding autonomous vehicles into this mix, while presenting its own difficulties, should not prove logistically impossible. Other obstacles come in the form of legal rights and public opinion. V OTHER LEGAL ISSUES A Use of electronic devices With regards to law enforcement, questions arise as to how to quickly visually identify autonomous against regular vehicles, for instance, with regards to the use of mobile phones and other electronic devices while sitting in such a vehicle. Nevada in 2011 adopted legislation to add another category to the list of exceptions for using a handheld device (such as a mobile phone) while in a vehicle: For the purposes of this section, a person shall be deemed not to be operating a motor vehicle if the motor vehicle is driven autonomously through the use of artificial-intelligence software and the 34 Road Rules 2014 (NSW) reg 24-1. 35 Jason Dorrier, Google Self-Driving CarsAre Learning to Navigate the Urban Jungle (13 May 2014) Singulatiry Hub <http://singularityhub.com/2014/05/13/google-self-driving-cars-are-learning-to-navigate- the-urban-jungle/>.
  • 17. 17 autonomous operation of the motor vehicle is authorised by law.36 Florida passed a similar law in 201337. Australia could adopt the same. B Liability Law Currently, great uncertainty surrounds autonomous vehicles and liability law. If such a vehicle causes an accident, who is at fault, the driver, car manufacturer or designer of the autonomous systems? In 2015, Volvo announced they would accept liability for any crashes caused by their vehicles, but, in many jurisdictions, the law remains unclear.38 Legislation passed in Nevada, Michigan, Florida and Washington DC limits the liability of a car manufacturer whose vehicles have been modified to drive autonomously.39 The basic rule appears to be that if a vehicle is at fault in an accident because of a flaw in the autonomous technology, the designer of that technology will be liable, rather than the driver or the maker of the unmodified car. Precedents also exist for other autonomous systems. A 2009 train crash caused by a malfunction of the train’s automatic train- control system led to 21 lawsuits and 84 out-of-court claims. 40 Australia should follow this obvious precedent. Manufacturers are unlikely to design, build and 36 Nev Rev Stat § 484B. 37 Fla Stat § 316.305. 38 Chris Ziegler, Volvo says it will take the Blame if one of its Self-Driving Cars Crashes (7 October 2015) The Verge <http://www.theverge.com/2015/10/7/9470551/volvo-self-driving-car-liability>. 39 Weiner and Smith, above n 9. 40 NathanAGreenblatt, 'Self-Driving Cars and the Law' (2016) 53(2) IEEE Spectrum 46.
  • 18. 18 market a new type of car if there is a chance they will all need be recalled after the first accident. Autonomous vehicles also bring complex moral equations into play. In one scenario, if an automatic vehicle faces a choice between hitting a little girl who has just run out onto the road, or veering off the side, possibly killing the passengers, how should it decide? What if it later emerges that the software was incorrect and the little girl was in fact a large dog? Strict ethical programming may have to be implemented by law before autonomous vehicles become widespread.41 C Drink-Driving Laws A possible use of autonomous cars is to reduce cases of driving under the influence of alcohol by transporting people home as passengers instead. As of 2012, 24% of drivers killed on Victoria’s roads had a blood alcohol concentration over 0.05 (by comparison, on average 0.3% of driver’s tested are above the limit).42 At present, Nevada’s 2011 law prohibits an inebriated driver from taking the wheel of an autonomous vehicle, and it appears no jurisdiction worldwide currently allows a drunk ‘driver’ to make use of one.43 This presents a curious contradiction, in that jurisdictions are permitting texting and even legally blind drivers to pilot automatic cars, but not inebriated ones. However, for the time being, it may be best to keep this precedent. No current car can be considered 100% autonomous. Even Google has not yet tested its cars in inclement weather or snow due to 41 Shane Genziuk, ‘Don’t Blame Me – Blame the Car’(2015) 38(2) Journal of the Australian and New Zealand Institute of Insurance and Finance 1. 42 Transport Accident Commission (Vic), Drink Driving Statistics <http://www.tac.vic.gov.au/road- safety/statistics/summaries/drink-driving-statistics>. 43 Nev Rev Stat § 483.
  • 19. 19 safety concerns. If the autonomous vehicle encounters an obstacle it cannot navigate, the driver is still expected to take control. It should therefore not be legal for a driver to be intoxicated if in control of a vehicle, even if it is at that moment driving autonomously. This area, however, should be subject to regular review. If, in the next ten years or so, completely autonomous vehicles emerge, delegating the ‘driver’ purely to the role of ‘passenger’ then the law might be changed. A distinction could be made between vehicles with or without a steering wheel for instance. In the United States, the National Highway Traffic Safety Administration (NHTSA) has proposed a formal five-stage classification system regarding autonomous vehicles of which only the final category is completely autonomous.44 Laws could certainly differ based on whether a vehicle is partially or completely automated. VI REDUCTION IN THE ROAD TOLL Reduction of the road toll is surely the greatest single argument in favour of autonomous vehicles, and explains the billions of dollars invested in research in recent decades. Globally, 1.3 million people currently die in automobile accidents every year, with another 50 million injured. Current trends are that middle and low-income countries will see an increase in traffic deaths of 83 percent by 2020 against 2000 figures, while for Europe and other high-income countries, that figure will decrease by 27 percent over the same period.45 It would be an exaggeration to say that autonomous vehicles will reduce the road toll by 100%.

  • 20. 20 certain number of collisions would seem to be inevitable. For instance, a tree falling in front of a speeding car which has no chance to brake. However, at least 90% of accidents are attributable to human error,46 something that autonomous vehicles may entirely eliminate. VII FUTURE TRANSPORTATION SYSTEMS Autonomous vehicles are expected to change our transportation system in a number of ways. The impact will be more than simply ‘cars driving themselves’ and avoiding routine accidents. Various techniques become possible in a system made up partly or completely of autonomous vehicles. A Vehicle Platooning Due to quicker reaction times, autonomous vehicles could be positioned much closer together on the road. Human drivers must typically stay two or three seconds travel time behind the car in front in order to maintain a safe braking distance. On highways, this can mean a gap of 50-100 meters. Recent trials have demonstrated that autonomous road trains could travel with gaps no bigger than 6 meters between the vehicles. By travelling more closely together, wind resistance and with it fuel costs would be significantly decreased, as well as overall congestion.47 B Higher Speed Limits Speed limits have slowly increased over the course of the 20th century. The United States had a 46 Ibid. 47 E Larsson, G Sennton and J Larson, ‘The Vehicle Platooning Problem: Computational Complexity and Heuristics’ (2015) 60 Transportation Research 258.
  • 21. 21 federal mandated speed limit of 55mph (90km/h) until 1987 and 65mph (105km/h) until 1995 before abolishing it entirely. Most individual American states now have limits between 70 and 80mph (110-130km/h).48 Aside from a few exceptions (such as the German autobahns), most countries are also in this range. This results in something of a contradiction, as most modern cars are capable of speeds well in excess of 200km/h. The two main restraints on speed limits are fuel efficiency and driver reaction times. However, it so happens that the advent of autonomous vehicles is coinciding with the introduction of electric cars. These cars promise considerably reduced energy costs, potentially removing both obstacles at once. A road system dominated by autonomous electric cars could see speed limits increased considerably to as much as 200km/h. The concept of speed limits could even be eliminated entirely in favour or simply requiring autonomous vehicles to decide on their own safe speed, as drivers are required on German autobahns. C Obsolescence of Traffic Lights and Other Traffic Regulators A major change in the road system could come about due to the obsolescence of traffic lights in a road system run solely on automated vehicles. Traffic lights (or else alternatives like ‘stop’ signs or round-a-bouts) are currently necessary at intersections to regulate traffic and prevent collisions. In a system comprising solely of self-driving cars, this may not be necessary due to a combination of inhumanly quick reaction times and instantaneous communications between them. If two self-driving cars are both approaching an intersection at high speeds, on course for a 48 Brilliant Maps, Who Are the World’s Speed Demons?: The Highest Speed Limits Around The World (16 March 2015) <http://brilliantmaps.com/speed-limits/>.
  • 22. 22 collision, it is not necessarily the case that one of the cars must stop entirely to allow the other to pass, as it would with two human drivers. Based on a simple communication between the vehicles, one could ‘agree’ to either speed up or (more likely) slow down as they approached the intersection. At a speed of 100km/h, a difference of less than a fifth of a second means the second car would miss the first by just over five meters – enough that the two would not collide. Such a ‘slot-based system’ is obviously impractical for human drivers. It could only be used in an intersection where only autonomous vehicles were permitted. This would decrease both travel times and road congestion.49 An issue does arise however, with integrating such a system with pedestrians, cyclists and other road users. Regulation 81 of the Australian Road Rules states: 81—Giving way at a pedestrian crossing (1) Adriver approaching a pedestrian crossing must drive at a speed at which the driver can, if necessary,stop safely before the crossing.50 This would appear to contradict the practice a slot-based intersection. However, it may still be compatible with Pedestrian Light Controlled (or ‘Pelican’) Crossings – equipped in Australia with the ‘little green man’ and ‘little red man’. Traffic would move seamlessly until a pedestrian pressed a button, at which point all the autonomous vehicles nearby would be ordered to stop. In addition to the above, a system composed solely of autonomous vehicles could see narrower lanes and reduced space required for parking.51 It could reduce significantly the 42 hours an average commuter in America spends stuck in traffic jams each year.52 Car-sharing could become 49 Remi Tachet,et al, ‘Revisiting Street Intersections Using Slot-Based Systems’ (2016) 11(3) Plos One 1. 50 National Road Transport Commission, Australian Road Rules (as February 2012) reg 81(1). 51 Bunghez, above n 3. 52 Jim Forsyth, US Commuters Spend about 42 Hoursa YearStuck in Traffic Jams (26August 2015) Reuters <http://www.reuters.com/article/us-usa-traffic-study-idUSKCN0QV0A820150826>.

  • 24. 24 VIII THE FATE OF HUMAN DRIVERS The combination of all the above factors makes it likely – if not inevitable, that humans will eventually be considered an unacceptable liability on our roads.54 The American Institute of Electrical and Electronics Engineers (IEEE) recently released predictions that autonomous cars will account for up to 75% of vehicles on the road by the year 2040.55 By perhaps 2050, there should be little obstacle, other than human error, to a road system with routine platooning of vehicles, ride-sharing, highway speed limits raised closer to 200km/h and many intersections integrated into a slot-based system without any traffic lights or other traffic regulators. Given these vast improvements in speed and efficiency, it will become harder and harder to justify the presence of human drivers. Perhaps starting with highways, and then spreading to the rest of the road system, human drivers are likely to face restrictions on their movement from about the middle of this century. Such regulation of our road system is hardly unprecedented. Already, upon entering a freeway in Australia, it is common to see signs with wording to the effect of ‘Start Freeway: No Pedestrians: Animals: Agricultural Machinery: Beyond This Point’ or ‘No Cyclists Permitted on this Freeway’. It is conceivable that similar signs could be installed within the next fifty years, with wording to the effect of ‘Autonomous Vehicles Only Beyond This Point.’ The detection of an independently driven vehicle would alert nearby vehicles to its presence, and perhaps cause a reduction in their speed. The police could then be dispatched to apprehend the offending driver. Sanctions such as a fine or loss of license could follow, much the same as under today’s road rules. 54 Stuart Dredge, Elon Musk: Self-Driving CarsCould Lead to Ban on Human Drivers (18 March 2015) The Guardian, <https://www.theguardian.com/technology/2015/mar/18/elon-musk-self-driving-cars-ban-human-drivers>. 55 Bunghez, above n 3.
  • 25. 25 A Legal Obstacles in Australia While it may make sense on purely safety grounds, the banning of human drivers may run up against an individual’s legal right to freedom of movement. This is a basic freedom originating in common law and also enshrined in s 92 of the Australian Constitution,56 stating: On the imposition of uniform duties of customs, trade,commerce, and intercourse among the States, whether by means of internal carriage or ocean navigation, shall be absolutely free. A number of cases have dealt with the precise meaning of this section. A distinction has been found between ‘trade and commerce’ and ‘intercourse’. Case law indicates that ‘trade and commerce’ includes such acts as ‘the mutual communings, the negotiations, verbal and by correspondence, the bargain, the transport and the delivery’.57 Intercourse, meanwhile, has a broader definition. In Gratwick v Johnson58, Starke J said that the people of Australia ‘are thus free to pass to and from among the states without burden, hindrance or restriction’. However, in Cole v Whitfield59 , the High Court indicated this does not mean that ‘every form of intercourse must be left without any restriction or regulation in order to satisfy the guarantee of freedom’. Mason CJ in Cunliffe v Commonwealth60 also said that the freedom of intercourse which s 92 guarantees is not absolute. Any law which ‘imposes a burden or restriction’ 56 Australian Law Reform Commission, Traditional rightsand Freedoms: Encroachment by Commonwealth Laws,Issues Paper 46 (2014) ch 5. <https://www.alrc.gov.au/sites/default/files/pdfs/publications/ip46_ch_5._freedom_of_movement.pdf>. 57 W & A McArthur Ltd v Queensland (1920) 28 CLR 530. 58 (1945) 70 CLR 1. 59 (988) 165 CLR 360. 60 (1994) 182 CLR 272.
  • 26. 26 on movement across a border would be invalid unless it was ‘reasonably necessary’ and the burden or restriction was not disproportionate to that end. It would be a matter of weighing the competing public interests. Given that 1,500 deaths a year are caused by vehicle accidents, it is readily foreseeable the High Court would consider this a ‘competing public interest’. If instead the High Court followed the earlier precedent in Gratwick,61 and decided that s 92 created a general freedom of movement, this may prevent autonomous vehicles completely replacing human drivers without a constitutional referendum on the issue. Indeed, it may be advisable for such a monumental change to be accompanied by a referendum regardless. Given current technological trends, such an event may occur in a timeframe of around 2050-2060. Regardless, it is easy to conceive of drivers making legal challenges to a law banning human drivers from certain stretches of road. B Other Jurisdictions Whether humans are effectively banned from driving, at least on certain stretches of road, may depend on the relevant constitutional rights and weight of public opinion in the jurisdiction in question. As we have seen, the Australian Constitution has uncertain wording on the issue. A jurisdiction like the United Kingdom has no constitution, however, it could call upon the common law or legislation, such as the Magna Carta62 or the English Bill of Rights.63 Indeed, art 13 of the Universal Declaration of Human Rights reads: 61 Gratwick v Johnson (1945) 70 CLR 1. 62 Magna Carta 1297 (Eng) 25 Edw 1, c 42. 63 Bill of Rights 1688 (Eng) 1 Wm & M sess 2, c 2.
  • 27. 27 (1) Everyone has the right to freedom of movement and residence within the borders of each State.64 In any country, which has signed the declaration, it could perhaps be used to mount legal challenges to any laws restricting the movement of human drivers. While not dealing specifically with autonomous vehicles, a number of cases have challenged other pieces of legislation restricting people’s freedom of movement. Of particular relevance would be a 2011 case from the American state of Kentucky. Eight men, belonging to the local Amish community, were charged for failing to abide by a recently passed law requiring them to display bright orange triangles on the back of their horse buggies. This was passed after a string of recent crashes between buggies and other vehicles.65 As the display of these bright symbols went against their religion, the Amish refused and were subsequently fined and, after refusing to pay the fines, sentenced to short terms of imprisonment.66 In 2012, the Supreme Court of Kentucky upheld the convictions,67 however, the state legislature also changed the law, allowing other alternatives to the orange triangles to be used.68 It is easy to see similar cases occurring, perhaps in another thirty or forty years, regarding manually piloted vehicles. Also noteworthy is the way the criminal convictions, along with subsequent public support (the men concerned were represented by the American Civil Liberties Union) compelled a 64 Universal Declaration of Human Rights, GARes 217A(III), UN GAOR,3rd esee,183 plen mtg, UN DOCA/810 (10 December 1948) art 62. 65 Ky Rev Stat § 189.820. 66 Jo Adetunji, Amish Jailed by Kentucky Judge over Warning Triangle Fine Non-Payment (17 September 2011) The Guardian <http://www.theguardian.com/world/2011/sep/17/amish-jailed-kentucky-warning- triangle-fine>. 67 Gingerich v Commonwealth of Kentucky 382 SW 3d 835 (Ky Sup Ct, 2012). 68 American Civil Liberties Union, Kentucky Supreme Court Upholds Convictionsin Amish Buggy Dispute (25 October 2012) <https://www.aclu.org/news/kentucky-supreme-court-upholds-convictions-amish-buggy- dispute>.
  • 28. 28 change in the law. The Amish population in North America is just 250 000 – less than 0.1% of the general population69 and it appears only a minority have objections to displaying any required symbols. More than any other factor, the weight of public opinion could delay laws to prevent humans from driving. Drivers currently make up the vast majority of the population. Another group worth considering are motorcyclists. As of 2015, of the 18 million vehicles on Australia’s roads, more than 800,000 are motorcycles, or 4.5% of the total70. At present, there does not appear to be any foreseeable way by which a motorcycle can become self-driving (given that the rider must mechanically move the handlebars and use his legs to steady the bike when stationary). If human drivers are to be banned from a stretch of road, presumably it will become off-limits to all cyclists and motorcyclists as well. One counter-argument is that motorcyclists pose little risk to other road users, given that in a collision, a motorcycle is less likely to cause great damage to a car or its occupants. For this reason, they may be allowed to continue riding, solely at their own risk. As a sign of things to come, the proportion of the population who have a license (in America at least) has been declining since the 1980s. Regarding young people, 69% of 19 year olds had licenses in 2014, compared to 87.3% in 1983.71 On the issue of banning human drivers, some polling has already been conducted. A 2015 poll indicated that 27% of Americans – a surprisingly large minority, would support restrictions on human drivers if autonomous vehicles were found to 69 Nate Berg, Why the Amish Population is Exploding (1August 2012) City Lab<http://www.citylab.com/politics/2012/08/exploding-amish-population-bubble/2795/>. 70 Australian Bureau of Statistics, 9309.0 - Motor Vehicle CensusAustralia (31 January 2015) <http://www.abs.gov.au/ausstats/abs@.nsf/mf/9309.0>. 71 Julie Beck, The Decline of the Driver’s License (22 January 2016) The Atlantic<http://www.theatlantic.com/technology/archive/2016/01/the-decline-of-the-drivers- license/425169/>.
  • 29. 29 be safer.72 IX CONCLUSION Given current trends, autonomous vehicles as a technology are likely to mature in the next five to ten years. Worldwide, there is widespread enthusiasm for their legalisation and many jurisdictions are already laying the legislative groundwork for their use. Given current trends, in developed countries at least, a steep decline in the road toll, perhaps close to 90%, can be expected in the coming decades. Australia should seek to adopt, as soon as possible, updated laws permitting the testing and eventual commercial sale of autonomous vehicles in Australia. The Nevada and California legislation should be looked at as precedents. While the individual states have to adopt their own legislation these should be as uniform as possible in line with the Australian Road Rules. Longer term, it is less clear that most jurisdictions will embrace the idea of a completely automated transport system. Due to concerns with freedom of movement and a general enthusiasm for driving, it may be a considerable while before completely autonomous systems become a reality, allowing changes such as higher speed limits and the slot-based traffic systems described above. Any country considering this should look at all the possible impacts, gauging public opinion as widely as possible, before making such a revolutionary change. If this does come to pass, no doubt legal challenges will emerge to any laws restricting the freedom of movement of human drivers.
