> 1) Efficiency. A flying car can theoretically take a straight line to its destination instead of having to follow a complex road layout. It might be less efficient to fly per minute, but if you're flying less minutes, it could be a net gain. Theoretically. That fact that standard commercial flights don't do that should be a red flag. Commercial flights follow pre-designated airways. Smaller aircraft in unregulated airspace aren't that constrained. But that's because there's too few of them.
