Self-driving cars are coming. Tech giants such as Uber and Alphabet have bet on it, as have old-school car manufacturers such as Ford and General Motors. But even as Google’s sister company Waymo prepares to launch its self-driving-car service and automakers prototype vehicles with various levels of artificial intelligence, there are some who believe that the autonomous future has been oversold—that even if driverless cars are coming, it won’t be as fast, or as smooth, as we’ve been led to think. The skeptics come from different disciplines inside and out of the technology and automotive industries, and each has a different bear case against self-driving cars. Add them up and you have a guide to all the ways our autonomous future might not materialize.
