I do suppose this could go into the racing forum but I felt it was more of a general question than about have being beaten by or beating a specific car or how to race.
But what's with people turning on their hazards when they either win or are passing to win a street race?
My best guess is it's like a form of mocking the other person..
i turn it on when i have an emergency and have to pull over to warn ppl and so they can see me
anyways yeah its more of an insult to the car behind, to me it means that the to the car behind "needs to pull over coz he's too slow"
