Science fiction has not been bothered by cars that fly, but planes that fly and land anywhere has been of interest.
The sport of hang gliding almost got the ball rolling until the soft wings invaded. Para gliders are not air planes, they do not have an air frame of their own.
An motorized ultralight glider ( airplane ) can take off in 50 feet and land on a dime, and with a little common sense we won't crash into each other with such deadly results as our "ground cars." Rolling weight across the ground is less efficient than moving weight through the air. Electric motors even solar powered electric motors are very possible and would restrict night flying. What about compressed air driven air craft?
First was our feet, then the feet of animals and now the fire of hundreds of horses driven mechanically buring fossil fuels.
When it comes to the formula for moving stuff weight is always a consideration.
The last time science fiction was concerned with flying transportation was with Icarus and Pegasus the flying horse.
Birds fly using the energy they have stored in their light weight bodies, and then they eat some more.
Its all about the fuel, and sunlight can produce power whether directly or indirectly say compressed air. How far did you want to fly your flying car?
