People who zoom up in front of me on the highway, in a big hurry to occupy the safe driving distance I'm trying to maintain, then they JAM ON THEIR BRAKES! Usually because now they're too close to the vehicle in front that's slowing down.

Or type-A maniacs, usually in full sized 4WD, extended cab pickups, who think they're driving a sports-car, and need to assert their manhood by cutting me off after I've signaled a lane-change or that I'm ready to exit.

Same types in big 4WD trucks/SUVs that ride my rear-bumper, flash their lights, and zoom around me because I refuse to drive 30 - 40 - 50 mph on snowy, icy streets. Often, they then find out that 4WD doesn't make their brakes work any better, after they have to stop by hitting the car in front of them!

Happy Motoring, Mark
