Was discussing at home (USA) this same idea that vehicle lights are brighter and drivers are less inclined to be bothered to dip. I rented a car in the UK several years ago which auto-dimmed the beam and was fascinated by the technology which would allow it to differentiate light sources and identify oncoming vehicles.

This feature must be old. My Subaru Forester 2018 has it. What non-US cars have are those new zone dimmable lamps.

Regardless I keep my auto dim off and just down. I don’t usually need the headlamps in high beam mode.

What would be useful is a taller median between both sides on a highway since often the blinding is because of a difference in the direction facing due to the grade of the highway. Facing people who are looking up a hill is awful.

It is true, that many drivers drive with the high beam on. My cabin is frequently illuminated by their lamps. My lamps never illuminate the cabin of a car I follow by comparison. This strange asymmetry does annoy me and I am certain I’m in the right but it’s usually resolvable by allowing them to pass.

This has been available in the US for a long time. I had it on the car I bought in 2016, and on another I bought in 2023. It's just not mandatory, so it usually comes as a part of some safety / driver assistance package. And even if you have it, you need to enable it.

I think most if not all US cars do this now. My current one doesn't even have a way to keep the brights on permanently. Now to wait 8 or so years for all the old ones to cycle out :(.
