I'm using the FISI2012 cars. When the AI make their pit stop to change tyres, sometimes they have very long pit stops. This happens to all the AI drivers but randomly. I have found that this is ruining most races especially when a driver is fighting for the win but then has a long pit stop. Of course long pit stops do happen, but not this regular. How can I make sure the AI pit stops take only 2-4 seconds all the time, rather then random 10 second stops?
