What stands out to me about all this eVTOL/air taxi vehicles are that they operate in 3D space instead of 2D like cars. This means, even though more inefficient than cars, you can have more “lanes” to operate in. On roads, you have to have traffic lights and stop streets, traffic itself, and cars driving inconsistent speeds or braking when turning. In the air this can all fall away, so people can live further away from city centres, streets can be left for cycling, and less concrete/asphalt infrastructure is required.
