I don't even use my high beams usually, and neither do I have LED, xenon or laser headlights. But I often do wish that I magically had brighter headlights without being an asshole, both in the city and rural. In the city any 2 lane or smaller road can be unexpectedly crossed by pedestrians, on crossings and not. And pedestrians nowadays are wearing all black, completely invisible on the side of the road. And on the rural roads, I want as far visibility as I can get, because the load is usually 1.5 lane, barely fitting two cars at below walking speed, so when I see an opposite traffic I need to immediately slow down and take to the right, almost touching the ditch or the wall, to pass safely. Additionally I need to spot opposing car in the dead corners, where there is zero visibility etc. And finally the same problem as in the city with pedestrians crossing rural roads, which is even more dangerous because it is unexpected and darker.

So I can see a powerful motivation to fit bright headlights in the cars, regardless of the other's comfort.
