As long as you pay attention to your mirrors, and don't drive into the back of cars that have lapped you, then I see no problem really. But I do think we should have a cut-off point in terms of lap time.
Have submitted my hotlaps to LFSW, and filled in the list on the spdo forum. I think I've done everything I can to qualify for the event. Now I just have to wait and see if I am accepted.
Put it this way, if I am accepted on pure pace, no one need worry as I'll end up spinning out anyway :P
