If autonomous vehicles start driving like humans, it's going to reveal the contradictions of US traffic laws. Traffic only works because humans break traffic laws all the time (e.g. speeding). Autonomous driving will either need to be programmed to break many traffic laws, or it's going to cause problems and block traffic. I honestly don't see how this is going to get resolved. The sensible thing would be to change traffic laws so they can be strictly enforced, like raising the speed limit to 85 on 280, but I don't see that happening.
