Street drifting is totally nuts. The video's of it I've seen from Japan are nuts, and the fact that kids here want to go out in the middle of the day and try it in traffic is even more insane.
I don't really care if you wipe out your own car, but I have to tell you that if your sorry ass runs into my car, everything you own will be mine. Now, and in the future. (It's called civil court and I'd fry your silly attitude there for as much money as I could get.)
If you have no insurance or assets, then I'd get my own insurance to cover the loss under UIM, and they would come after you for the money they paid out.. (Want a nice 300,000.00 bill on your head for life? That's what my insurance UIM limits are.)
If nothing else makes you wake up and take notice, the prospect of paying off some huge debt for the rest of your life should bother you. (No more Supra because you could not afford one. Get a bus ticket and go to work, you have bills to pay, but you get NOTHING. Just the bills, and it takes many years of asking "Would you like fries with that" to pay off a insurance settlement. (Do the math, 10.00 per hour into 300,000.00.... oh, and they are going to charge you intrest too dude.)
That being said, I like the idea of having fun in your car. Just do it when there is nobody else around. Or get to a track and have fun. (not very practical for 99% of us.) Find a new housing tract, just when they have paved the streets, but don't have any houses built yet. Great place to have fun, and since you can see the whole place usually, it's easy to have one person watch for the PD, so you don't get busted either.
Good luck. And stop drifting in traffic.
