Best race track with AI?

Hello guys,
I only bought this game a couple days ago and I'm searching for some race tracks that are good to drive with AI. Please link some.

 

There's a good NASCAR circuit mod called ATE-Ona raceway but the original mod got taken down so you can download it from other websites BUT ONLY AT YOUR OWN RISK!
However there is pikes peak https://www.beamng.com/threads/pikes-peak-lidar-edition.51052/
Toban raceway which should have AI support: https://www.beamng.com/resources/toban-raceway-rfactor-2-conversion.5552/
And a pretty good one https://www.beamng.com/resources/lakeside-park-raceway.10895/
