Well, this is all linked to economy...
  • Supersonic flight costs a lot more than subsonic
  • Flights to the moon cost a lot of money and you don't make a penny out of it

This is obvious that progress alone does not drive decisions. Money does.

As for your flying car, you'll start seeing it when we have drivers who can safely drive on 3 dimensional roads, and for that, you have to be able to do it safely on 2 dimensional roads first, which can be far, far away...
