The guys I hate are the ones who come flying up behind you and, even though you're already doing above the speed limit as it is, get pissed because you won't speed up even more for them so they start riding your bumper. Then they finally tire of that game after you flash your lights at them a couple times, so pass you in the other lane, pull in front and then SLAM THEIR BRAKES.
Yeah, if I hit you as a result, guess whose insurance is footing the bill, love muffin?
