When driving, what gets the most in your nerves?

Haha, I don't want to write an essay about this, so I'll just list them all:

1) Tailgaters - I go freaking 20 km/h over the speed limit and people are still riding my ass!
2) Taxi drivers - omg, these guys are going to run over someone one day. I always see them going right through stop signs, just so they can get to their destination as fast as possible
3) Old people, chinese people, and women - holy shit, these are some of the worst drivers I have ever seen. Old people drive too slow, chinese people drive too slow and go all over the road, and women go fucking 800 km/h on a 50 zone!
4) People who slow down during turns and don't speed up while turning - I've crashed about....oh.... 7 times because of this. The guy in front of me is turning, now thats ok, but when the guy is turning and goes soooo slow while turning, I go nuts because Im trying to go around the guy, but he doesn't speed up. COME ON!
5) Psycho drivers - these guys are all over the roads, trying to get to work on time. You're late, its your fault. Don't kill me because of it.

Wooo, that was fun.

Jam it back in, in the dark.
