There will never be a practical flying car.
The problem is 98% of the people can’t handle 2 dimensions, adding a 3rd will be a blood bath.
The sad part is if flying cars ever do become popular, in the left lane of the top lane of 50 vertical lanes there will still be some @$$¶º|£ driving slowly and blocking the fast traffic behind them.
Saw one of those idiots the other day- left lane doing 50 with a bumper sticker- “Get off my ass, I’m saving gas”. Fine, want to be a jackass and go under the speed limit- do it in the right lane.
Absolutely.
