Ridesharing has replaced hitchhiking as a new mode of transportation. Where hitchhiking was anonymous, unpaid, and fell out of favor in the 1980s, ridesharing is planned, paid for, and built on online trusted communities through ratings and reviews. This level of trust has enabled ridesharing services like Uber and Lyft to grow exponentially since 2007 by addressing issues of safety, reputation, and payment that anonymous hitchhiking could not provide.
