I don't understand why this still happens. How have car manufacturers still not realized that they need to polarize their displays in the opposite direction? Tons of people wear polarized lenses, especially for driving! It's not even a niche use-case, like half the options my optometrist offers are polarized, they're everywhere. And the fix is so incredibly simple - just rotate some of your manufacturing equipment 90 degrees. Boom, done, problem solved.
This has been quietly driving me crazy for years.
I would simply prefer my car didn't have any screens at all. If a new car just powered off the screen while not using the backup camera it'd have my attention so fast.
The monkey paw curls...
Your next car has you looking into a solid piece of metal, lacking a windscreen. 😅
I'm moderately surprised that Tesla hasn't already tried replacing the windshield with a big screen and cameras tbh
It's a tank?
Tanks have windshields. They’re just tiny and made of very thick glass.
In this picture the windshield is right below the main gun:
From a technical standpoint it doesn't matter which way something gets polarised. Trouble is that some manufacturers do it one way and others the other way. Which means that it's not standardized. Having it be mandatory to do it one way and one way only for a given product would solve that issue because then it would be correct every time. Barring the one or other Monday where someone for some reason messes it up before noticing.
Yeah, it's bizarre that this isn't something that's been standardized yet. Things you look into should be polarized one way, and things you look out through should be polarized the other way.
If the EU can sort out USB-C, maybe they can fix this mess, too.
Instead of trying to standardize screens, standardize the glasses lens at 45°. Now every screen is half as bright but no screen is black. Assuming the manufacturers of the screens dont also decide to rotate their polarization to 45°
