I've just re-read this. It's honestly like Aerohead doesn't realise that 80-90 percent of drag is caused by high pressures pushing backwards on the front surfaces of the car, and low pressures pulling backwards on the rear surfaces of the car.
Decrease those pressures on the front, and/or increase those pressures on the back, and you have less drag.
We
don't have to compare the pressures to other shapes; we simply work on changing the pressures on the car we have.
Maybe he needs to watch the video?
