I haven't seen this posted here, and I've only tried this on B-spec in the Dream Car championship, but there's a strange bug that often makes the championship a bit of a joke.
When the track loads and you can see it is raining the AI cars all start on dry tyres and will absolutely crawl round the lap, but you can change to wet tyres before the race and you'll fly away from the rest of the field. The AI cars will pit for wet tyres at the end of the first lap but by then your lead is huge. My Bob has even lapped cars at the Nurburgring while they're still on their first lap after about 17 minutes.
Then, if you go to the next race and it is dry the AI cars will start with the wet tyres they had on at the end of the previous race. They are almost as quick as they are on dry tyres but they all pit and change to dry tyres at the end of the first lap, gifting you another large lead.
If it is raining every alternate race then the whole series is a cake walk. Big money too for winning the series.
