Comment on Why have we as a society just accepted the increasingly blinding bright lights of cars?

FYI you’re going to get absolutely shredded by technical responses about how light works.

So the basic premise is that LEDs on their own can make polarized light. So let’s say for example that we make all car manufacturers produce cars that have their LEDs horizontally polarized. So they shoot light that is horizontally polarized. Then we force them to make their windshields be vertically polarized. That way, no matter how much luminous power comes out of everyone’s car you won’t be able to see it. It should probably be the other way around with lights making vertical and windshields blocking horizontally.
Ok but now, how do you actually see things? Well light is funny. When you hit objects with light polarized in one direction you’ll get scattered light back which will contain some light that is correctly polarized to pass thru the windshield.
For this to work, you just need to standardized the polarization direction.
You could even wear polarized glasses if you’re a pedestrian. The house at the end of the Culdesac can have their windows polarized too and so they wouldn’t be blinded by every car coming thru.
