Awesome, but....
You should definatley be able to leave burnout marks. You should make another like this only have it be a race between other cars and stuff, you could have cones and stuff be to track markers and if you hit them you get time taken away or somethin. Aweosme idea, i had a few minutes of fun with this one. So, in conclusion 2 ideas, burnouts and racing! And you coould probably have like a race mode and a demolition mode and then you could incorperate the crashes. Very, very good idea!
