Which self-driving car companies are going the most miles without human intervention?
California serves as the home for many automatous car trials, where 28 companies were reportedly conducting active tests on public roads in the state in 2018, according to the website The Last Driver License Holder. In California, that means 467 vehicles were operated during that time, driving more than 2 million mi in autonomous mode. A key part of the testing process is known as “disengagement,” which is the moment a human safety driver regains control.
