Completely agree that the reason we don't have flying cars is because most people aren't capable of flying.
Two Aggies are flying in an airplane and the engine dies.
One of them says, "Oh no! We're out of gas!"
How high up are we?
10,000 feet!
Nobody's ever gonna find us up here!
Aside from most people not being able to fly, the problem of not maintaining vehicles would be a disaster.
Quite right.
Texan friend insists your Aggie passage is a true story ;-)
