After many tries I am finally happy with it : ) It still need some finetuning, specially at the beginning of a race, but its getting there. Skidmarks and grass marks should be available again on a future version, with the new AI a lot of things changed behind the scenes and I need to re-implement it.
I agree 100% with the music, I end up silencing it and its not a good sign haha I have some nice loops from a rally prototype that I was working on but they are short and might end up in the same spot.
