This fixes a lot of problems. No more cars flying off into the woods at Burnenville. No more pile ups at the dogleg heading into Stavelot. And most importantly, the AI don't ride the guardrails after La Source. I've raced multiple races of 10 laps and there is usually only about 3 to 5 AI that don't finish the race. The AI do slow down a bit at the bottom of Burnenville but this is a serious upgrade in my book.
I was i bit disappointment to find cars still DNF-ing after the update (i should have tested more...).
The right kink to Les Combes is the culprit i suspect. This will be fixed in the next update. The slowing down at Burnenville will also be looked at.
Because of the long straights the corner entry- and apex speeds are usually sacrificed to ensure the best exit.
