I hope European-style adaptive headlights become the norm in the USA eventually. Some higher-end cars have a matrix of LEDs instead of one bulb per headlight, and they can programmatically dim just some of the LEDs. If you have your headlights on but there’s a car in front of you (or on the other side of the road, whatever), the high beam will dim just the area the car is in. This happens automatically while you’re driving.
This is an option in some European vehicles (or may be standard on high end ones) but they have to explicitly disable the feature when exporting to the USA.
The USA did approve something relating to this, but it must not be sufficient since the European manufacturers are still disabling the feature in the USA.
From personal experience in Europe, I can tell you that it sounds great in theory, but it’s horrible in practise. I get routinely blinded by headlights here and I feel like it has only gotten worse with the advent of LED headlights.
Interesting, I have those on my car and I actively avoid using them.
It can’t cope with anything more than a simple scenario (dim around car in front, deal with on coming car in other lane). If you also have pedestrians and vehicles on side junctions, then you burn their eyes.
So, I’d assumed it was a US feature (straight, wide roads) brought over here
