Can you get the AI to run your setup?
I think so. It's a bit of stuffing around with special events.
1. Copy your setup to Steam\steamapps\common\assettocorsa\system\setups\tatuusfa1 (call it what you like, e.g. imola.ini).
2. Copy folder Steam\steamapps\common\assettocorsa\content\specialevents\SPECIAL_EVENT_26 to a new folder called SPECIAL_EVENT_99.
3. Edit event.ini in there to change the track, model, cars in the RACE section. Take out all the SKINs (They will be for the F458), and put SETUP=imola for each AI car
And then ram into the back of the AIs every time they're way to slow in a corner.
