I'm a really easy going laid back guy, but man, I get seriously angry when I'm in the car by myself.
I hate people who stay in the exit only lane until the very last second and then attempt to merge. Hey, jackass, do you want to know why there's congestion? Because of geniuses like you.
I hate people who don't use their turn signal, and get over whenever they feel like, even if that means you have to strategically hit the breaks to avoid hitting them and also not getting hit by the people behind you.
I hate people who don't know how to merge. Don't try and merge onto I-5 at 30 miles an hour, it just ain't smart or safe!
I hate people who SLOW THE FUCK DOWN whenever there is ANYTHING on the side of the road. Yes, yes, a car has it's hazards on. Yes, yes, there's a cop an accident ON THE OTHER SIDE OF I-5! Good lord, I should slow down to 20 miles an hour!
