True. They're very annoying, though, especially the guys who get behind me in my little Corolla in a jacked-up pickup with the BRIGHTS on and ride my bumper. There are some places (especially in the winter) where it's hard to just pull off and let them by, especially when they're BLINDING me.
Had some guys do that to me when I was driving home one night earlier this summer (even though I was already going more than the speed limit), and then they roared past me at a sharp curve, yelled at me and gave me the finger, as if *I* was doing something wrong. I almost went off the road. Took me a long time to simmer down.
