That's no excuse! They'd be expecting everything to be "too cheap to meter" nuclear, if not Mr. Fusion.

Secondly, it's about size and form factor. what is a flying car? a hybrid vehicle designed to be able to switch between being a ground vehicle and an aircraft.

George Jetson's flying car folded up into a briefcase. The '50s people continue to be disappointed in your lame excuses!
