I had it typed up all nice and then it got deleted....

So, basically save your time, effort, and the appearance of your vehicle and leave your side mirrors attached.

Not quite. That was 7 cents/1000 miles from unaerodynamic mirrors on unaerodynamic cars. If we can make the stretch from that to aerodynamic mirrors on aerodynamic cars having the identical drag costs, then 7 cents/1000 miles in the days of 25 cent/gallon gas equals $1/1000 miles in today's $4/gallon economy. $1 every 1000 miles is $150 over the lifetime of my vehicle.

I researched side mirror requirements in the western states I drive in. CA, NV, AZ, NM, & TX only require one rear view mirror and one side mounted mirror giving a view 200' to the rear. None of them state that side mirror has to be mounted outside the car.

CA & one or two of the others have outside mirror requirements if the view back through the rear window is blocked by anything except passengers.

Some states, like NC, clearly do have outside side mirror requirements. Caveat ecomodder.
