Like others have observed, a lot of work-around for just a little gain.

Automobile drag coefficient - Wikipedia, the free encyclopedia
Quote:
The combination of drag coefficient and area - drag area - is represented as CdA (or CxA), a multiplication of the Cd value by the area.
I guess this is the crux; how much larger can you make the mirror body for the sake of smooth flow before the surface area drag undoes the gain?
