When I had some window tinting done on a car, they tinted the side mirrors at no extra charge with excess film.

At first, I didn’t like it, but quickly grew to quite like it. (It’s pretty much only annoying for seeing the curb while parallel parking at night.)

I don't think tinting is the same thing as electronic dimming.

It’s not the same mechanism, but they both reduce glare and one is wildly easier than the other to get installed for someone bothered enough to wear sunglasses on night drives.
