> Flying is much less energy-efficient than driving on a solid surface Small aircraft get 10-20 mpg, and the world record is over 60 mpg. Energy efficiency might be a reason why ground transport would continue to exist, but I'm skeptical that it's the fundamental obstacle to "flying cars" And since there is a lot more space in the air than on the road, the "self driving" problem is probably much easier. It's true that the failure modes are a lot worse, not just for human error but for mechanical failures. But it's actually somewhat plausible to me that 100 years of unregulated innovation would have given us some kind of personal air transport. > With strong AI this proposal is particularly dumb Yes. So of course AI development is pretty much the only thing in the world that isn't regulated at all. Does this increase your confidence in regulation as a social technology?
