What happens to a flying car after a fender-bender? More efficient to buy a fleet of cars to stash at airports.
If these vehicles become popular, it will be raining cars.
Every time there is an accident, someone on the ground will be at risk of having a flying car fall on their head, or their home, or their office building.
If you think the skies are crowded with airplanes, just imagine what it will be like having flying car traffic over head.
Somehow, I don’t think people have thought this through.
Err... like Hertz and Enterprise do already....:^)
