Thanks to my testers for their work so far. Here's a list of comments on the points they brought up, which also serves as a to do list for myself:
[as designed] cones: due to AC's horrible physics for them I made most of them uncollidable.
[done] the loo: yeah I'm wondering in which of the kn5s that is. I've noticed it before too. should just be removed. if you can, could you check in which kn5 it is? otherwise I will once I get around to it
[?] fans: I am not 100% happy with their look either, but I don't really know what to do about it. I feel like the mix of shirt colors is realistic. I'm open to suggestions on how to make them look better (screenshots from other tracks where they look better would be helpful).
[as designed] gamermuscle: I think visually they work quite well actually, better than expected. The deal is that he will show it on his channel, so its ads for publicity.
[?] I might add Sim Racing Paddock banners as well / same deal.
[as designed] occlusion map baking: I think it's a lot of work to do that. Maybe in a future version, but not for this one, sorry.
[done] improved TV cam: need to check it out and I'll put it in if I like it
[done] remove side_l and side_r csvs
[done] put fans in its own kn5
[working on it] still need to finish the grass
