The mirror can contribute so little to overall drag that it would take a very expensive,world-class full-scale wind tunnel to measure the difference,with and without.

Well either way, I am still curious of the effect of mirrors on window down driving. Does it make sense that no mirrors would increase induced drag from the open window? Or would be it be just as unnoticeable as the mirror delete itself?
With lack of instrumentation it is really hard for me to tell if there are any positive effects from the mods I am doing. I think the passenger mirror delete helped as that tank I got 46mpg, the following tank was only 40mpg but I had a lot of not normal driving for the first 100 miles.
Before I took off the passenger mirror I bought a panoramic rear view mirror and I have to praise that little gem, I can see 2 lanes over and have no blind spot at all on the passenger side...it does take a little getting used to, but it surely helps visibility. Even if put the passenger mirror back on, I will still be keeping the panoramic one...
