As an aside, here's an example of a racing incident from last night and how it would be handled. We ran seven races in series last night as another dry run. First, here's what happened.
Drivers:
CrazyBMXer-silver M3
Bimmer-white E46
Open-red RX8
Me-green Camaro
Going into turn one (where all the accidents seem to happen), I was a bit hot, and saw that I was going to rear-end open if I wasn't careful. I lifted throttle, and had to tap the brakes. They locked up momentarily, as indicated with a small puff of smoke. Bimmer saw the writing on the wall and went inside.

Bimmer hit the grass, and understeered coming back onto the track. He made contact with me, and we both went sideways.

Crazy had nowhere to go. He took some engine and suspension damage, and all three of us took at least a little aero damage.

After the series ended, Open and I went into the replay and watched the incident several times, coming to the conclusions above. We didn't do anything during the race, which was only 3 laps. If it had been an enduro, we probably would have done laps 1 and 2 under caution, allowing Crazy to pit with minimal consequences for the rest of the race. We decided that this truly was a racing incident, so no points deductions would have been warranted.
