It does bring up the question of what’s left in car design.

RAM jets?

A car could get 10–30% better energy efficiency than a conventional car at the same speed. Initially, the air jets would reduce and then eliminate wheel drag, and then hold for safety maneuvers. At speed, off-wheel-lift would be generated aerodynamically, with the option to also spot redirect air pressure from the RAM jet, or the air jets.

Then 2.0 would be the fully redesigned one-eyed two-seated flying Tesla Bodywingster.

All for the environment!
