The Jetson's flying cars depending upon some means of anti-gravity. Which doesn't exist because gravity is not a Newtonian force as much as it is an Einstein huge mass warping time-space.
Once you put wings on a car it is no longer a car, it becomes an airplane that's regulated and licensed by the federal government instead of by states..
