At least when I see the underglow LEDs I think "ha that's kinda cute, wonder when he's getting pulled over". Those don't bother me as much.
And there's nothing we can do about it. The aim of the lights can't be adjusted. Unintended consequences.
On the other hand, why do we have a new car? Because the old one got written off. Why? Because one of those gigantic SUVs whose hood is at about chest level, with way bright headlights was tailgating and blinding the spouse from behind so she pulled over to let it pass. Only to have the driver lose control (it was winter with some ice/snow on the road) and hit her on the rear corner. If it wasn't for those high-mounted, blinding lights none of this would have happened.
Since headlamp alignment has a legal requirement to meet I don’t see how it could be road legal without adjustability.
That exact scenario is why I think self-adjusting headlamps which were standard on most Xenon equipped vehicles should be required for all HIDs whether Xenon or LED.
However, if it’s noticeable you probably should have it adjusted or the rear ride stiffened.
I see three major categories of blinding lights on the roads in California:
New cars that are really bright and with appropriate beam shape/cut-offs, but annoying on hills or because of the taller cars you mentioned.
New or not-so-old cars where the driver is using the wrong light settings. That is fog lights and/or high-beams in inappropriate conditions or sometimes the opposite: somehow having daytime running LEDs at night instead of proper headlight activation.
The aftermarket retrofits which have none of the appropriate beam shape/cut-offs or projection. This can be a bit like the daytime running LEDs above in being diffuse but much brighter and often obviously anachronistic on some older car I know is from the basic halogen sealed-beam era. But it also includes trucks with various "offroad" lights being inappropriately activated on streets.
