Those things fucking suck! Last card I had had one and it took like 30 seconds to a minute to darken. Next car I made sure had the old school flicky doohickey.
We’ve had them in a few cars. What we’ve found is that the “perfect” amount of dimming varies from person to person. Same car, I thought the dimming logic wasn’t aggressive enough, while my wife thought it was too aggressive (or the reverse, I don’t remember). The manual mirror avoids this issue entirely.
Well, auto-dimming rear-view mirrors have been a thing since the 90’s.
Your idea layers onto that, and I’m sure it would require trivial amounts of power (watches have used LCD since the 80’s).
I’m pretty sure I’ve seen LCD used as a dimming method for windows.
Yeah, but the window ones require a lot more power hear. No idea how the physics and math work out.

I dunno, the one in my 06 Jetta worked really well whereas the one in my 13 Subie doesn’t seem to do anything
