I don't see how flying cars will work, I mean think about security, there's nothing to stop people go over a fence or a wall. Also everyone is going to have to get a flying lience, not drivers! It's all going to be very complicated, and one of those things people in the 1950s thought would happen in the year 2000, and it hasn't! Now people say it's going to happen in another 50 years, which I doubt!

Also imagine how much it would cost to develop roads to work with flying cars, if there will be roads all across the world! Trillions! Not worth it IMO!
