Passenger carrying drones are all the rage. The are lots of articles detailing the progress of these (VTOL) Vertical Take Off and Landing vehicles - most of which use battery powered electric motors for propulsion - so I have decided not to repeat that information here. It is important to note that these vehicles are NOT true carplanes since they CANNOT DRIVE through adverse weather or restricted airspace. Maybe some day they will but nobody seems to be proposing that now.
