Well, needs more work.
After Griffins bend/Turn 2 in the curved left leading to the 2nd gear left, cars on the inside crash hard to the cars on the right and 9 out of 10 times there's a mess there. In the following section of the road, cars can't run well side by side. They hit hte barrier and spin out.
Previously, the AI was very slow getting down the twisty bit on top of the mountain. Now they're too fast. I can hardly keep up. In the first and last turns, the cars are much slower than before.
