been in one, my ex girlfriend was driving, we got cut off by some jock type storiod rage people in a civic
she flipped them the finger, and cut them off in return, we are sitting at a red light, they pull up behind us and get out of the car....we took off like a bat out of hell, turning up side streets, running signs, and lights, in the end we got ahead of them, pulled into a driveway, and killed the engine, they drove right by.
I never give the fingure in the car anymore
