I would think the most likely use for evtol (assuming, for the sake of argument, that whatever sci-fi technology needs to be invented will be invented to make it cost effective) is autopilot flights that are currently long commutes with a lot of traffic -- ie: Suburbs to city center and back, or long cross suburb trips.

Autopilot with strictly regulated maintenance and no personal ownership is about the only way it works, assuming your neighbors don't care about the noise
