I think the idea is pretty cool, but I also think it can be very dangerous and very expensive and may take jobs away from people. What is the world coming to? Are we that lazy that we can't operate our own vehicle, or is technology that great? If technology is that complex then maybe we should try to invent other things like a robot that would fight our wars; well not exactly that but we should invent things that might actually be needed. Something that might help us in the long run, instead of some thing that could possibly retard our driving skills.
