I think im in trouble with the police can past experiences help me?

First off, let me say one thing, im never doing it again!!! I came out of a tyre shop that a mate owns, still in his driveway I ripped a massive burnout in my new car. The fire department came amd I took off. Nothing happened to anyone, they left after...

they realised it was me. They were beside me at the lights saying something but I just drove away and ignored them.

A few days before that, I was racing around a small community called clemows orchard and did a handbrake skid. They came out and got my plates and claimed to my girlfriend that they were going to the police.

I know that this is stupid, im a guy and I just have the urge and I dont know why!!! I am never going to do this again unless it is legal (on a racetrack or in a skid contest) and I was wondering if I am actually going to get a knock on the door one day. What will happen to me if thay do? Will I lose my license or my car? Help!!!

I would say lay off for now
im a girl and I love cars and going fast
lets just say the 08 saleen super charged bullit goes over 250 you can get in serious trouble
your liscence will go bye bye and your car can be imponded
if you gonna street race go into the middle of no where wher you know there are no cops and have fun ... thats what I do
enjoy your car enjoy burn outs and skids but Dude don't get in trouble w/ the law

cheers. I know, its a s*** load of fun!!! I do a lot of tray drifting aswel, go to youtube and search traydrifta
