I’ve found the angle of the other car with newer headlights is very critical for how bright they are. If they are angled up at all, like the camber of the road at an intersection, coming around a curve with a steeper crown on the asphalt, or even a car with weight in the trunk or a full rear seat, it’s enough to tilt the lights up enough to be blinding. The focus edge is so sharp it takes very little to get overwhelming light from modern car headlights.
