You're right that the hard part about understanding for consumers why "deep carbon wheels" perform so differently is the variety of ways in which the air passes over them. Tire as leading edge, tire as trailing edge, tire as leading and trailing edge(think top and bottom of the wheel), the way in which the wheel "pushes" air. It seems to be easier to say "yay, carbon wheels are fast" than to actually consider how the wheel moves through the air and how the tire effects the system as a whole.
