everyone will use drones. Right now, we use car, because we dont know how to create compact & safe flying transport, like flying cars or hover boards
Maybe this will happen somewhen after we solve fusion energy. But so far, primary reason to stick to ground transport is that flying eats much more energy. That, and also safety issues.
It would suck because of the area exposed, I suppose you'd weather vane into the wind.
Perhaps it is skinny front view and the volume goes vertical like a fish body.
Also there could be a mother ship blimp beaming energy to them via deadly microwave radiation.
The other thing too I brought up with somebody else is to use muscle wire or memory wire and put that into blades that are otherwise soft. So if it's about to strike something the blades go limp.
