Same question as always applies: how much energy does it use compared to a car that drives on a road?

The article does mention electric (or hybrid) power, but since electric cars are a thing now, when comparing alternatives it seems like this would not have the lowest energy usage.

The Uber Elevate white paper answers many of these basic questions [1].

Bottom line:

  Conventional car about  1 mile / kWh
  Electric car about      3 miles / kWh
  Electric VTOL about     2 miles / kWh

How much energy does a car use compared to a horse? I get your point and I agree with you, but that is probably not the right question.
