In florida, you can be pulled over for it. I've done it a couple of times, but unless there is a special occasion, like I have to take a major sh*t, I wont do it. I heard it's easier if you dont have your rear mirrors installed. i"d much rather sit back, and look for pretty girls, lol
Just make sure you can get to the front of the line, and make sure you look both ways before launching. Many people run yellow turning red lights, and if you launch hard as soon as it turns green, you're going to get creamed. Just fyi..
