through a glass darkly

You know how most cars have rear-view mirrors that can be dimmed by toggling between two reflective surfaces? Why have I never seen a car whose side-view mirrors could do that?

They also have technology that can adaptively dim light (automatic sunglasses, for example). I've never seen that used in cars either.

I'd say it's most likely because it'd be alot of work, and you'd have to flip all your mirrors twice a day, if you drive that often. It'd be a hassle.

It'd be a hassle.

For me, it'd totally be worth it. Maybe blinding headlights in one's side-view mirror is more of a problem around where I live because of the denser traffic.

I would totally pay an extra $500 or so for this. I have had times where I have just stopped using my side mirrors at night, tipping them out of the way so they were useless, because the blinding effect from headlights made it nearly impossible to see the road. This is pretty clearly unsafe; I have no idea why nothing has been done about it. With all the new halogen headlights out there that are ever brighter, it's just getting worse.

I've seen the auto-dimming tech in cars for the rear and side-view mirrors. I think it was a friend's parents' big ol' Cadillac that had it. The friend said it was mostly pretty good, although there was the odd time when it went dark because of bright headlights at night and he couldn't see anything for a bit afterwards.

I've never seen the flipping dual-mirror tech in side mirrors, but I figured that's because flipping those would be non-trivial and thus more dangerous than the short-term blindness. I suppose there are ways around that, but if people won't generally pay for the feature, it'd be too much expense to figure it out and test it to be sure it was safe.

My M Coupe has an autodimming rearview mirror and I wish the sideview mirrors did the same thing....perhaps on the more upscale beemers they do such a thing. The traditional flip mirror actually gives you 2 images all the time, but the second image is of the poorly illuminated roof of your car so it's not a problem. I suspect that technology would not work very well on the outside mirrors where they are in bright sunlight. The electronic auto-dimming mirrors are definitely the answer. The problem is that most folks don't think about the problem except when they are being blinded by their side mirrors at night, so the automakers aren't exactly inundated with requests for that feature. I, too, have sometimes diverted my side mirrors at night because of the glare, but that's realy not a very safe solution.
