Even if this could be made to work, which it can't with polarization, it would still show huge disregard for anyone in an older vehicle or any other mode of locomotion.
Then maybe not in the windshields but in glasses and contact lenses.
Wouldn't the filter also end up dimming the things you are trying to see?
Yes, I think it would. Polarized light typically remains polarized when it reflects off a surface. (It’s a complex interaction so not always)
that's easy to fix, just make the light brighter
Wow... Fuck cyclists and other road users, I guess!
