Yes, in the air I'm expecting a very different scenario than on land. No pedestrians just an element of collision avoidance for birds, all vehicles legally required to be broadcasting their position to an automated air traffic control, probably maintaining 100 meters between vehicles versus road traffic being 1 meter from oncoming. In the air it would be almost a pre-planned route with a 50 meter collision avoidance corridor. Plus an emergency landing site selection process, potentially the ability to land on water or an emergency parachute.

Part of the reason I found the paper I linked to be persuasive is that they predict the EVTOL aircraft only needing 2-3x the total energy of an EV. The energy cost in dollars could be less than gas for an ICE vehicle making the same trip. There are very light aircraft with 100HP engines, I'm picturing something light and birdlike.
