A video in the "I was wrong!" thread reminded me of something I was thinking a couple of years ago but never made a post about.

The idea is that if the flow is turbulent, the air traveling with the car will be mixed with the air nearest to the road, and that this will lead to momentum transfer from the car to the road.

This could be minimized by delaying the onset of turbulence, but without testing it's hard to estimate the magnitude of the effect.

Thoughts?
