> it's really hard and no one is actually that close to useful AVs My suspicion is that the thing everyone's going to founder on is that a large part of safely operating a motor vehicle on the public roadways consists of observing and then predicting the behavior of all the drivers, cyclists and pedestrians. So you need to either have true AI, or somehow get all the humans on those roadways to stop behaving so erratically. The problem is, one of those is currently impossible and the other is currently infeasible. (I'm not sure which is which, and I'm not sure it matters.)
