We already have flying cars, they're called private helicopters. We most likely are not going to "flying cars" in the way high-scifi portrays. These are the 3 major problems that immediately jump out to me, 1) we have a lot of gravity on our planet that vehicles are going to have to fight to stay airborne, 2) vehicles **MUST** have at least a certain mass in order to function and be safe, and 3) the resource cost in terms of energy and material for every single person to have their own flying car the way people have and use cars today would be mind boggling. That last point is really what kills it for me.

Maybe they could be rented? Like you just take an air taxi when you're in a hurry? (and can afford the fare)

And they only land on top of big buildings, so you either live in one or take a ground taxi to the nearest big building, then an express elevator to the roof?

I could see a world where this is common, but it costs a couple hundred bucks or so - possible for most people to do it occasionally and a few to do it often.
