Update: sorry guys! I had a lovely day with my friends, and I really needed it.
So, I didn't do today's worth of investigations, but I can do tomorrow.
For Grand Valley, I'd like to see everyone on slightly better behaviour. I know that Cape Ring is an exceedingly difficult place to race, and I'm glad that a majority of you were careful and clean, but I hope that you know, I'm watching for patterns. If you consistently drive in a slightly unpleasant way, I'm going to nip the problem soon.
Specifically, T1 and the double-apex right hander at the end of the lap, at Grand Valley East, must be done right. I don't want to see anyone in the sandtraps on the outside of the track in either T1 or T7 (entry to double apex right-hander/final corner.)
If you push someone off of the track, and into the gravel/sand, your penalty will be more severe than normal, including a possible time-calculated (30 seconds) stop-and-go penalty. Again, that slows the car you're bumping down more than normal, so the stewards will slow you down way more.
When you're practicing, get used to focusing on braking sooner than the other cars in front. It's a rule in the OP, I expect everyone who isn't trying a legal pass to brake sooner than the other cars in front.
