Semi related, but in rainy weather (Washington), there's plenty of times where I'm basically guessing at the line location. I'm not sure if I'm especially bad at it, but with light reflections all over the place, I lose track of those little white lines.

This gets made worse then construction strips old lines and draws new ones a couple feet over. The old ones in dry weather are barely visible, but in watery weather, they hold water differently than normal road surfaces.. meaning there are now lines which, due to different water levels of normal road surfaces, form visible lane lines competing with the real lane lines.

The reflective bumps are a huge boon for me when they exist. I'm always surprised more accidents aren't caused by poorly visible lines.
