This isn't well informed -- Mirrors are a substantial source of increased drag. Something like 5% of the air resistance of a vehicle comes from the outside mirrors -- over the life of a car, that's worth several hundred gallons of gas, and across the population of cars, several billions of dollars in savings to consumers. I fret about the longevity of the technical solutions (mirrors on cars from the 60s work as well today as they did when they were installed) but it could be a huge boon.

Wouldn’t removing the front mirrors cause helmholtz resonance[1], aka annoying “window drums”, when the front window is rolled down? If you’ve ever driven with only the rear windows down you’ll know what I’m talking about.

If you're doing that, you have introduced a far larger source of turbulence than the mirrors ever could produce.
If you're doing what? I don't follow
