You don't understand the roadways in Illinois. If I'm passing 6 people in a row in the left lane going 10 mph faster than them, and some dude comes up to me doing 90, I'm not moving over right until I pass all 6 cars, which might take a while and definitely rustles their jimmies.
I move over all the time for considerate drivers, but if some dude is driving like an ass, I'm not going out of my way and putting myself in danger to accommodate for him.
