I've had requests not to use the word "urban" in daily conversation because of its "racial overtones". I guess if I was rich enough to sell planes it wouldn't matter as much.
This looks like a fun little thing; but I don't see "flying cars" ever happening, at least not under human control. All them other fools on the road now are out to kill you; do we really want to increase the volume of space from which they can attack?
