Truckers piss me off all the time! Once I was run into the median on a four lane highway, and another time one pulled out in front of me and I almost went under the trailer "Smokey and the Bandit" style. So I'm sittin there stopped, honking until he get's out of my way, and HE flips me off. So I yell something out my window to him and go about my business. Ten minutes later inside a McDonalds some old, fat, bearded, hick (the trucker) taps my shoulder and starts talking S***. Well, to make a long story short, I punked his retarded ass out in front of all the McDonald's workers and they all start laughing at him. Dude looked like he was going to have a heart attack.
Anyways, DC2's right, it's a good idea to "assume nobody sees you."
