Here a new version of ai_hints for 1980s ++ cars for Glendale(KnR97) Club and West.
AI was going too hard on the jump and the chicane, mainly concern supercars and racecars with lot of power and stiff suspensions.
Just copy the files to your track folder, and overwrite.
If you want to use 1950s-1970s ai_hints just rename it ai_hints and change the name of the one you was using to ai_hints modern, 1980s++, as you prefer.
Have great battles.
