that a good question, sometime I find when racing against some big names you want them to continue, this would be a great change, could it be possible that all cars AI with problems such as oil, water, engine, sus, trans, break, throttle, lose wheel, punture, are told to pit.
yes not very realistic I must admit but with game in mind limping back to the pits to be fixed won't earn them any points ether it just keeps them in the game, so maybe a small program to switch back to pits for all failiers would be nice, now I wish I'd taken that programing course!
