Almost Year Before

Before Matrix there was Speed
The film tells the story of the LAPD cop who tries to
rescue civilians on a city bus rigged with a bomb
programmed to explode if the bus slows down or if
civilians try to escape.
Trapped aboard the ship, Annie and Alex
work with the ship's first officer to try to
stop the ship, which they discover is
programmed to crash into an oil tanker.

SpyCarACT
(July 21, 2015)
SPY Car Act, the legislation introduced by Markey and Blumenthal
The Security and Privacy in Your Car Act (the SPY Car Act) specifies that the
NHTSA and FTC together issue
•  Notices of Proposed Rulemaking within 18 months, and final regulations
within three years of the act’s enactment.
•  The SPY Car Act will apply to vehicles made two years after final
cybersecurity and privacy regulations are issued.

SpyCarACT : Cybersecurity Standards
•  Vehicle System Security. All entry points to a vehicle’s electronic systems must be equipped with
reasonable measures to protect against cyberattacks, including isolation measures to separate critical and
non-critical software systems;
•  Vulnerability Testing and Remediation. Such reasonable security measures shall be evaluated for
vulnerabilities following best security practices, including appropriate applications of techniques such as
penetration testing, and must be adjusted and updated based on the results of such evaluation;
•  Data Security. All driving data9 collected by a vehicle’s electronic systems must be reasonably secured
from unauthorized access while data is stored onboard the vehicle, in transit from the vehicle to another
location, and in any offboard storage or use; and
•  Real-Time Attack Mitigation. All entry points to a vehicle’s electronic systems must be equipped with
capabilities to immediately detect, report, and stop unauthorized attempts to intercept driving data or control
the vehicle.
Violation of such cybersecurity standards would result in liability to the federal government for civil penalties of
no more than US$5,000 per violation.

SpyCarACT : Privacy Standards
•  Transparency. Foreclosing other notice mechanisms as legally viable, the act would require that
each vehicle provide clear and conspicuous notice, in clear and plain language, to owners or
lessees of a vehicle of the collection, transmission, retention, and use of any driving data collected;
•  Consumer Control. Owners or lessees must be given the option to terminate the collection and
retention of driving data without losing access to navigation tools or other features or capabilities, to
the extent technically possible (with the exception of driving data stored as part of the electronic
data recorder system or other safety systems required for post-incident investigations, emissions
history checks, crash avoidance or mitigation, or other regulatory compliance);
•  Limitations on Driving Data Use. Manufacturers may not use any driving data collected by a
vehicle for advertising or marketing purposes without the affirmative and express consent of the
owner or lessee, which must be obtained using a clear and conspicuous consent request in clear
and plain language that does not make use of the driving data a condition for the consumer’s use of
any nonmarketing feature, capability, or functionality of the vehicle.

With 'recall,' Fiat Chrysler makes its car hack worse
The decision of Fiat Chrysler to mail out USB sticks to customers directly to patch the
recent vulnerability is the security equivalent of waving a red rag to a bull
"It's like if after surgery the doctor forgets a pair of scissors in your stomach, and when you find out, he just sends you a
scalpel to fix it yourself."
July 27, 2015
Why Chrysler's car hack 'fix' is staggeringly stupid
http://www.zdnet.com/article/chryslers-response-to-car-hack-was-slow-and-incredibly-stupid/

Recall Costs.
GM's total recall cost: $4.1 billion
U.S. Department of Transportation's National Highway Traffic Safety Administration
(NHTSA) sets the national safety standards and can influence -- or in some cases order
-- an auto manufacturer to repair safety-related defects at no cost to the consumer. Even
if the fix is something as minor as a missing washer or a faulty electrical connection, the
manufacturer stands to lose millions of dollars in the process
In their interviews with manufacturers, some identified difficulties in notifying vehicle owners about
safety defects. For example, there was mention that not all vehicle owners keep their address
information up to date with state motor vehicle registration offices. In addition, the older the vehicle,
the more changes of ownership and mailing addresses occur, making it more difficult to identify the
current address of the current owner.
Toyota's Out-of-Control Gas Pedals, cost of the blunder $5 billion

WillAutonomous Cars Be the Insurance Industry’s Napster Moment ?
Autonomous vehicles will make commuting a lot safer.
Consumers have to pay out a lot less money with the lower number of claims,
but premiums will necessarily drop as well and the overall amount of money
within the car insurance system will dwindle.
One opportunity for the industry could be selling more coverage to carmakers
and other companies developing the automated features for cars.
When the technology fails, manufacturers could get stuck with big liabilities
that they will want to cover by buying more insurance.
There's also a potential for cars to get hacked as they become more
networked.

1996+ : Year the Matrix Started.
Modern automobiles are laced with a number of microcontrollers
and sensors that monitor and control everything from the throttle
position to the ambient air temperature.
These devices typically communicate over a wired in-vehicle
network like a CAN bus.
CAN bus is one of five protocols used in the on-board diagnostics
(OBD)-II vehicle diagnostics standard.
The OBD-II standard has been mandatory for all cars and light trucks sold in the United States since 1996

Ethernet Becoming a Standard
Ethernet is now being considered as a replacement for legacy bus protocols such as MOST and
FlexRay by car OEMs including BMW and Hyundai.
Ethernet could be the catalyst for
bringing the automotive industry a step
closer to connected vehicles,” says Frost
& Sullivan Senior Research Analyst,
Divya Krishnamurthy.
Broadcom has helped set up the OPEN
Alliance special interest group (SIG) to
promote BroadR-Reach as a de facto
automotive Ethernet standard.
CAN network doesn’t have enough capacity to carry the encryption overhead necessary to carry and protect messages
effectively. From both angles, performance and security, we see a role for Ethernet in the eco networks

V2V : US to push for mandatory car-to-car wireless communications
The government believes vehicle-to-vehicle data links will help improve
driver safety, and will push for legislation requiring it in "a future year."

NHTSA to require backup cameras on all vehicles
Start phasing in on May 1, 2016 models and be at 100% by May 1, 2018.

Over-the-air software coming soon to your next car
Tesla's OTA upgrade bumped up the all-electric
Model S's 0-60mph speed by about one-tenth (0.1)
of a second. Tesla CEO Elon Musk tweeted about
the upgrade, saying it was an update to the
inverter algorithm. An inverter changes direct
current electricity to alternating current.
We have a software and firmware team that packages
updates. The packages are matched to a VIN [vehicle
identification number] to ensure the car has the
required hardware to receive all relevant updates

ECU Module Consolidation
Adding a new ECU for new features is no longer sustainable.
Dedicated processors, memories and other electronic components for new features
increases cost and architecture complexity, says Thomas Wendt, Senior Partner in
Roland Berger’s North American Automotive Practice.
The solution he suggests is module consolidation. This approach would leverage modern
technologies to add speed and flexibility to vehicle electronic architectures, while saving
cost. The consultancy estimates at average $175 per vehicle for cockpit electronics.
