Proven in testing..
Close windows and run the air conditioner on the highway. Aerodynamic losses
from open windows create more drag then the AC uses.

Open the windows in town traffic.  The AC uses more power from the engine
than any losses from aerodynamic drag.  (open windows have very little drag
effect in normal town driving speeds.)

Of course there always is the small problems with in town traffic at a
standstill and radiated 120F heat and the exhaust from the big truck/SUV
next to you and in front and behind.
