The route is okay. The problem is that the steering lock of the AI vehicles is much too low. The original SimBIN vehicles in particular have this flaw.It's amazing... the only problem for me is in turn 1... where the AI is quite bad
If you can fix this it would became one of the greatest circuit to race in this game... but it's 5 stars anyway, thank you for your work.
Open the .hdc files for vehicles with a text editor. Scroll down to the section [CONTROLS], and write these numbers in:
SteerLockRange=(5.0, 0.5, 57)
SteerLockSetting=38
Do this for every vehicle, and the AI will no longer have problems with sharp 90 degree or 180 degree curves on any route
