I drive a lot at night on I-70 between Denver and Green River. Visibility of the road is a big issue in the areas of tight curves. When I used to have an older car with weaker headlights having to step on brakes abruptly for not being able to tell which way the road ahead curves used to happen periodically.

Over the mountain passes in spring where the lane markings get worn down sometimes you just can't see anything w/o high beams (and risking to blind the oncoming traffic).
