The burden of proof to prove otherwise falls on Julian Edgar.
Which brings us back to MetroMPG's admonition about limiting any claim with respect to a case-specific basis.
Aerodynamics of Road Vehicles 5th edition shows different drag and lift figures, as measured in wind tunnels, with/without wheel rotation. Interestingly, when I looked closely, the results weren't always worse with wheel rotation - but they certainly were different.
