lol funny story, same thing happened to me today...going through a 2 lane left turn and this guy next to me just starts coming into my lane...so i move onto the shoulder and lay on the horn...funny thing is, i pull up to the next signal with my window down and scream "get outta my lane you jack@$$", i finally turn and look....its one of my buddies that just bought a new car and wasnt paying attention...
i was like man, you really pissed me off lol
