Agreed.
As for the person making the 10mph comment: agreed also. My cut-off for speeding is usually 10 over. If someone rides my ass at that speed (i.e. 75 in a 65, 80 in a 70, etc.) you'd better believe I'm gonna be engine breaking to f**k with them, and then flicking them off as they drive by.
But my absolute greatest pet peeve HAS to be two people (especially on a two lane road) in separate lanes each doing the same speed. On a five lane highway it's not quite so bad, but if you're in the passing lane and you aren't passing someone...then MOVE OVER, DAMMIT!
I also hate the way Georgians drive in the rain. Water on your windshield does not mean you have to drive 30mph on the freeway. Sorry. If you can't go faster than that, then stay inside until it's dry. You're endangering everyone else on the road with your slow driving and spaztic breaking technique.
