But... US and UK/EU is just not ready for such things. Can you imagine all the bad drivers we have on our roads taking to the air in these things. Crashing into power lines, phone lines, tall buildings. Trying to move along above streets at night and hitting every wire across the roadways. Some sort of phoneline/powerline heads up display sensors would be needed to show them up as red/orange at night etc and to have them all programmed into the vehicles gps somehow. But GPS would need to be far more accurate. Something the EU GPS system should be when it comes fully online.
It will be a very chaotic period of transition from road to air vehicles over a a couple of decades or more as the governments try and re-write highway codes to cover these new types of vehicle. Both single, dual or more seats and of course the hoverbikes.
All dropping out of the skies when they fail and killing people and crashing into the roof tops of houses etc.
It will happen in our lifetimes. I still want one one, although maybe a hoverbike.
