Looks like you may have found a bug if the CPU is forced to go through the pit lane - cheers. Will look into this and sort in a future build - may be hard to replicate right enough.
Also, in Monsoon conditions, going through a tornado knocks you off course randomly which explains why you swerved @ 5:25 and why Blue was naff in the cat and mouse.
I get the impression you are no longer challenged by the AI. You seem to be racing in wet conditions most of the time and I think the AI is probably a little bit too cautious. I'm sure it can be improved so will look into this also.
