I think the issue is more about the angle of the lights than their brightness. lowbeams are only supposed to illuminate a fairly short distance in front of the vehicle. this is a big problem with lifted trucks. the owners don’t bother to realign the lights.

Even "properly" aligned headlights are a problem on trucks, because they're too high to begin with.

> Vehicle size is another issue that comes up regularly, since NHTSA regulations for headlights don’t include a standardized mounting height, even as cars have ballooned in size in recent years. This means a perfectly aligned headlight in a larger car can still wreak havoc on a smaller car

Lowbeams on sedans are blinding me in my small truck (not lifted, headlights aligned as intended). Something must be done.

except when they go over a bump, or a hill. or when they break and give gas, or when the car is loaded, or when they hit something and it's permanently bent, etc...

and then there's the internal adjustment knob that most people are clueless about. and most of the rest just put it on full high angle, because they see better that way...

society is fucked, and this issue is just sign #4745...

It's also a big problem with hills. If two cars are approaching the crest of a hill at the same time, (IE each one is pointing up hill, facing each other) then each one is going to be blasted by each others low beams.

This does nothing when the ground is curved the wrong way, which happens often enough. Hills are already dangerous enough and blinding people whenever the second derivative of altitude is negative isn't helping.
