It’s mostly the color of the light that’s the problem right? Our brains register the cooler light in the contrasting darkness as blindingly bright as opposed to warmer incandescent light, despite both lights having the same measured brightness (lumens).
I do not think so, the LED lights are just really bright. The human eye is most sensitive to green light. And according to the following graph similarly much to reddish and bluish tones (maybe even more sensitive to the yellow stuff rather than blue) https://www.researchgate.net/figure/The-eye-sensitivity-function-7_fig17_343319896
Supposedly car manufacturers even brag about their stupid bright lights, so I do think they put effort into making their lights more and more bright, even if they try containing the beams to the street. I couldn’t find Mercedes’ original ad to this picture though: https://knowyourmeme.com/photos/2556223
