Tbh, I think this rule adds a totally new element to endurance racing. Don't forget, this is an amateur league, almost a feeder towards true, unrestricted endurance racing amongst the fastest drivers in the world, this just encourages competition, IMO. At least with rules like this, it's not the end of the world if you're at the end result of a pile-up, which will actually encourage teams to continue racing, rather than giving up when 2-3 laps down. It's hard for the big teams to have a huge lead wiped out by a SC, of course, but in contrast, it's a great test of skill to discipline yourself, and manage safety cars, and other disadvantages during the races to succeed, you don't really find this anywhere else, as far as I know, and I'd love it to stay in the rules.
