Twenty years ago I interned in a small robotics company, and one of scientists there was a Phd from Berkeley. He had done his thesis on dynamic controls for autonomous vehicles. I was asking him a bunch of questions, and at the end he just said that it's a moral question, and that they've already solved all these problems -- "you just connect the cars together physically, and it's called a train". I thought it was pretty funny and insightful.
