at our backwater out in the sticks track we've had more than a few cars roll off the end of the track. now days on a raceday, we have a removable section of fencing which allows errant racers free access to the bush which also goes uphill. the bush has two clear tracks that go further into the bush each time we have an oopsy. none of the cars that go bush have any major damage, just a bit of bush rash from the spikey gorse bushes. nothing a good car painter can't fix.
