And from his studies, that is far too steep an angle to be beneficial.
For it to work in reducing drag on regular cars, a diffuser would need to angle up only a few degrees, say like 5°
Also depends on length, height of the underbody, and shape of the rear of the vehicle - see the drag rise on an estate ...
