I figured out the AI "congestion" problem so in order to have a much more realistic race against the AIs I recommend using these values:
AI limiter 0-2
In the AIW file:
AIRange=(0.4000)
AISpec=(1.0000,0.0000,0.0000,1.0000)

Do you have any tips how to setup an AI race in order to see the field spread out?
I tried aggression at 20-50, limit at 0-50-100 but it doesn't change anything, all the cars are bunched up.

Thanks for the track:
A question: could you make a more realistic night lighting like here? https://www.youtube.com/watch?v=g6cSwvAKYfo
Because right now it's too bright especially the crowd.

There is also AI improvements in this track (not the online one)
AI will now be good to race against. AI now enter pit safely. But DO NOT use yellows.

I found how to make AI go further on tyres. That will be updated in 2016 skins mod once the tracks are all updated.

I did quite a few 200 lap races against AI. Full 40 car field, yellows off, invincible as it's easy to be punted by AI. Awesome fun, it's truly like a conveyor belt.

Machine makes some of the best tracks on RF2!
Thank you!

A.I in RF2 are not designed to work well with Ovals... as almost any modder would know.

This is very good, do you mind if i port it to Assetto Corsa?

Really sorry guys, somehow got on private. It is set back to public now.

To fix current AI issues, the only option is to use 2 track versions. A 20 car limit version with pits only on the front straight. And a 40 car version with walls adjusted like Martinsville with a back straight pit entry and exit. It's something I may look at next year if S397 has not given us reworked AIW capabilities.

Thank you!

Known issue with AI entering pits, but the pit needs to fork from main path after sector 1 timing line. Until S397 update AI code I can't fix that.
As far as AI crashing, not sure why. I ran a 100 lap race with 20 AI, none crashed.

Any tips for the AI? They just keep crashing, on top of that the pit entrance line they use is awful!

Thanks :D Boogity, boogity, boogity, lets go racing boys!

Not a straight conversion from my original SCE track. All new road surface, infield and walls. Including different radius corners at each end as per the real track. Adjusted grip levels (less in corners than straights until tyre loads fixed)

It's bristol baby!

Thank You
