> .. the cheapest and most effective option for private transport for both individuals and whole society will be via flying cars .. When driving any distance, I frequently see cars stopped on the side of the roadway. They’ve run out of fuel, had an accident (maybe very minor), had a mechanical problem or even a flat tire. If these were flying cars they would be full of serious casualties. A problem in the air that puts a “flying car” into free fall results in approximately 80 km/hr of additional velocity within 2.25 seconds. If the “car” has even a modest forward velocity the results will be fatal. At low altitudes there is going to be no way to effectively put on the brakes. Well one might think, why isn’t this a problem for planes and helicopters? Oh but they do have this problem caused by gravity, and they solve it with big wings or rotors, sophisticated avionics, trained and redundant pilots, special places that have room to land and take off, air traffic control, etc. The difficulty of addressing the safety problems of vertical take off and landing, flying below glide speed, collision avoidance, small size, and extreme reliability prevent even the military of from building such things.
