The flat plate is obviously the worst-case scenario.
Beyond a bullet-shaped front, what most car mirrors approximate anyway, the gains are made at the back.
A carefully designed mirror-car body blending (Opel Vectra / Vauxhall Cavalier ? can help reduce drag and noise, while being ahead of the mirror plane.
If you look at mirror housings, some are tapered at the rear - at least on the C30/S40/V50 range Volvo used this trick.
