BTW, the lack of commercial success for flying cars has nothing to do
with propulsion methods.

But propulsion does matter, in the sense that there is no affordable
way to make a flying car. Helicopters get terrible gas mileage.

You do know helicopters spend a fair amount of time not traveling, don't
you, but that has nothing to do with flying cars.

Cars spend a fair amount of time not driving, too. So?

Not at close to full output power.

Helicopters don't have a throttle or an "off" button?

Of course they do but your response shows you know absolutely nothing
about helicopters.

When a helicopter is hovering, the engine(s) are at close to full power
output without going anywhere.

When a car is not moving, the engine is at idle.

Get it now?

And it still has nothing to do with flying cars.
