You want someone to fly a miniature aircraft at over a hundred miles an hour with hardly any pilot training? Or are we gonna force them to pay $100k+ for flight school first?
Put simply flying cars are horrible. Dangerous projectiles piloted by idiots or untrusted AI guzzling fuel and/or electricity and an absolute FAA nightmare.
Could probably program them to pop onto "rails". Will never happen until we got a real robust power source. I think bitcoin miners might punt on cold fusion, that'll shake things up.
