Also, I think every car I have driven in Europe has a knob to adjust the height of the headlights. It seems like it is a requirement, but it might not be. On the other hand, a 2007 entry-level Skoda Fabia would not have it unless forced by regulation.

Adjust the lights too high, and you will aggressively be flashed by the opposite traffics high beams.

It is and has been for 30 years (76/756/EEC).

Usually you can't adjust it high, because the purpose is to lower the beams when the boot is loaded (and thus the car is not sitting level). "0" should be the standard / reg level for a level car.

IIRC, Xenon headlights are required to dynamically auto-level because mis-adjusted ones were considered too dangerous. I'm a bit surprised that's not the case for LED headlights. The issue with manual adjustment (or even semi-automatic) is an uphill or a bump in the road will flash whoever's driving the other way.

I think a few luxury models have a local dimming feature, so they automatically dim the section facing other cars when detecting them.

That dimming is only on when the high beams are on.

If you drive a BMW and have Adaptive LEDs and the right camera you can unlock that feature. When I drive with the high beams on and it detects oncoming traffic it turns of the left beam.

And LEDs and Xenons are auto-leveling. Fun fact, Xenons required washers, but LEDs don't.

Thanks for the reminder, there is that knob! Another thing that the MG had was automatic high beams when on a dark road, so it would pop on and off at the worst times. I think I had to fiddle with that same knob to turn that off, guess that knob has grown up a little
