Matrix headlights that automatically notch out oncoming cars have existed for years - but are banned in the USA.

> but are banned in the USA.

No, they've been allowed for 2 years now, pursuant to a law passed November 2021.

What's allowed is not implemented by any cars yet because the us standard is far more demanding than the European standard

Some Ford F-150s have them. They can be enabled with a software tool. They are amazing!

"banned" is not quite the right explanation. More "deemed not good enough". Source: https://www.cnn.com/2024/02/15/cars/headlights-tech-adaptabl...

It's not only oncoming drivers that can be blinded.

On my car it works for bikes and people too.

On my car it works from behind other cars as well. There's a tree lined road near me, drive behind someone at night and there's a dark box around them, with the the trees being fully lit up.

And it also works with over-reflective road signs, they too get a dark box.

I thought that the matrix functionality was only for high beams.

Also, they're banned in the US? What the fuck?

Matrix headlights practically don't have separate high and low beams. It's a different setting for the same projectors.

The avoiding functionality works up to a limit even on low beam setting in my car.
