One of the promises about flying cars was speed: you would theoretically be able to live in LA and commute to SF. So there was definitely some amount of disruption talk. With that said, this is sort of the point: SDVs would be close to arms reach of pedestrians virtually all the time, so I'd imagine that when all is said and done, the safety/regulatory barrier ought to be an extremely high hurdle to overcome. There are many things that we can talk about in terms of "if only X was solved, that would change the world" (e.g. X being the cure for cancer, or X being singularity, etc). But the devil is of course in the details: until we know what X is, it _could_ be a single breakthrough but it most likely is a nearly insurmountable wall of a million factors). For SDVs, X is L5 autonomy.
