And look how some people drive and are unable to see in two dimensions to see what goes on around their car. Now you add a third dimension.
Agree. And it's worse than that. Cars live in a 2D world where there are 2 degrees of freedom (forwards-backwards and left-right). A flying vehicle adds 4 additional degrees of freedom (up-down, pitch, roll, yaw)... so much more that can go wrong.
When it comes to flying cars, I am not as pessimistic as everyone else here seems to be, but I don't see how Joe Public can be entrusted with one. I think there either needs to be a trained and licensed pilot, or the vehicle needs to be self piloting.
