I'm still waiting on my flying car, it should have been here by now.
The tech exists but do you really think that the politicians and the insurance companies and the manufacturers are ever going to allow individually owned flying cars with our DUI population? If the DUI’ers have issues with driving on a 4 dimensional plane(length, width, depth, and timing) just imagine the accidents when DUI’ers can’t contend with 5-6 dimensional space(length, width, height, depth, timing,and perhaps course or heading).
The FAA would try to assert juristiction....oh it would be just a mess!
