Most of mine are driving related, and these are from before I started driving professionally.
1. People who do not use the 2 way left turn lane (or suicide lane) correctly. When you pull from a driveway into the center left turn lane, it is there to increase speed so you can merge into traffic. It's Not.. I, repeat NOT there so you can stop and wait for traffic to clear. "Hellooooo stupid one... I am in the driveway behind you and now I can't move because your dumb a$$ let the traffic on the left catch up to me again.. Thanks!!" The reverse is also true. The lane is there so you can pull out of traffic flow, slow down and make your turn. NOT so you can slow in traffic, then pull into the turn lane 10 feet before your turn.
2. People who see that you are in the fast lane in traffic and are quickly overtaking their position, yet pull in front of you and slow down/block you in. Cmon people.. The fast lane is called the fast lane for a reason. go fast or stay out....
3. Gangster slang on the internet... what the heck is "iz" I can see croping certain words to save typing, but for crissake its the same number of letters!!! It doesn't make you look cool... it makes you look stupid.
4. Phil, you got that right about getting to the point. My mom is like that. She will make a 45 minute conversation out of a 2 sentence statement. Ugghhh...
Edit:
5. People who merge onto the freeway 30 miles per hour slower than traffic flow.
6. Since I started driving the truck I see this all the time.. People merging on the freeway slower than traffic, yet are clearly ahead of my rig. I have to slow down for them, but they slow down for me at the same time.. now we are fighting for whos going to go the slowest. People.. Trucks are hard enough to stop and start as it is.. if you are in front, GET ON IT AND GO!!!
7. People swerving all over the road while yammering on the phone.. HANG UP AND DRIVE!!!
8. People who leave their high-beam lights on while comming at you from ahead.
8b. People who have misalligned headlights that point directly into my mirrors.
