> uber for robot planes will beat any ground bound system "Beat" as in get to the destination faster, but the ground system would probably be cheaper (use less energy) as it doesn't have to continually expend energy fighting gravity. Perhaps if traffic conditions are very bad (e.g. stop-start driving with no regenerative braking) then the air option would be cheaper.
