re: What % of drivers know that "drive right" is the law?

Here are some related variants of the theme that drive me nuts as well: the guy on the 3-lane interstate who is driving all the way left and slower than traffic - Hey Buddy, you're AT LEAST one lane too far to the left. The guy who comes barrelling behind you in the left lane when you are passing and you are nice enough to get over and let him blow by...who then goes on to go much slower than he was going when he bore down on you, thus impeding you! The guy whose speed varies so much, that he forces YOU to keep passing him and/or letting him pass. I drive with cruise control almost 100% of the time on the interstate, so I know it isn't my fault!
