Unsure of their potential use at the moment, or what they're really meant for... The 'hint' label says "
May improve loading speed" - so it could be a function that may assist lower-end hardware, perhaps... Began to encounter AI issues on track sometime back, and was suggested to deactivate this tab entirely - with no further issues to date...

Just did a test - it worked on track-day and race modes with a few cars on the grid... No issues with the start - all cars pretty much bolted on green... By any chance, after removing or deleting those files from the tracks' AI-folder, did you 'reload' the track or restart CM again for those changes to take effect? Can I also suggest to uncheck the 'New AI behavior' tab completely (CM/Settings/CSP/New AI behavior), restart CM and do another test... With your response, include use of: car type, track name & track mode - I can then replicate your settings to test at my end... All the best.
