I think Lex might be correct, that self-driving cars is more difficult than it might appear at first, because of all the edge cases plus meta model of society needed. I hope AI will be successful at driving cars but I want a both/and approach where I can drive the car manually if I want to and like crazy and if there is any danger then the AI kicks in. And at other times when I'm lazy I can just let the AI do all the driving.
