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.
- fingerlocks 7y agoWouldn’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.

- Piskvorrr 7y agoIf you're doing that, you have introduced a far larger source of turbulence than the mirrors ever could produce.
