The era of the self-driving car has arrived, with the shiny promise of fewer auto collisions—and the inevitable potholes of a transformative technology. Despite the significant concerns raised by a recent accident involving a driver’s reliance on a partially autonomous automatic braking and steering system on the Tesla Model S—one of 70,000 such vehicles now on the roads—the auto industry is roaring ahead with autonomous vehicles (AVs). Google is testing its driverless cars extensively on U.S. roads; General Motors has teamed up with car-sharing company Lyft to develop a driverless taxi service; and most major automakers will be releasing fully or partially autonomous vehicles in the next five years.
