Been there, done that. Managed to walk away each time though, can't say whether it's luck or judgement those times, and I don't want to repeat the experiment to find out!
I used to do that. Then I got old cars that cost 300 quid for a wing... Contrary to what my passengers might tell you, I now take it alot steadier! Besides, I work on the theory I've had enoguh crashes to find my limits now, so I shouldn't go over them again... :)
