I do have some concerns about polarizing the light. If I can get a hold of some cheap filter material I might be inclined to do some tests. Maybe I can rescue the polarizer out of an old LCD TV.
Polarizing’s not completely magic, It does seriously reduce the amount of light coming in. There’s just usually enough light around that it doesn’t affect us, our pupils dilate a fraction of a fraction and it’s no big deal.
But at night when there’s already relatively little light out, It does reduce the overall light amount.
I’m also concerned that any light that bounces off something but maintains the polarization will be blocked, so there will be a higher chance of you not being able to see some percentage of your own headlight illumination, I would think that the average diffraction off everything in front of you would thoroughly destroy the coalescence of polarization but I don’t really know for sure, it’s possible that would make your own headlights less effective to you.
I suspect if we were thinking about this in the '50s if it were viable somebody would have pulled it off by now. But we only have had windshield sized polarizers in TVs for maybe a decades so maybe?
I know. It’s not my idea, this is old old. So its amazing how much we seem to like people crashing at night.
