No,there's no problem since this car, as is, will never hit the public roads.
Eventually it will need to land somewhere in front of a home or some other building.
6 seconds of gas, 2 to 6 hours to refill, and 80 kN of thrust shooting out the back. The engineering is crazy, but imagine using that in traffic with a motorcycle right behind you.
Is FSF (full self flying) next?
LOL maybe but I'd be more interested in FSL: Full Self Landing. Taking off is one thing, finding somewhere safe to land in traffic is another
I guess it would be better than having somebody pass you on the shoulder.
