There seemed to be a lot of confusion, leaving the parking lot, with people not sure who was going next. Usually the driver of the SAG wagon ensures orderly flow. Each group woud fire their engines together, then pull out in turn.
I can just see the third group, ”Let's swap places in line. You're seeing too many sites, this tour.”
The V8's don't run off and leave the 2.8's? I'd figure, all out, the 2.8's and 2.5's would rapidly fall behind. From the brake zone to the center, the heavier cars may suffer, but from the center down the straights, the faster cars should be gone. Of course, anyone familiar with the course would have an advantage.
