No DNFs for AI / AI DRS Train

Having the same problem in my F1 driver career. Have done 6 races so far, not a single DNF, not a single spin or crash or even little mistakes. The AI makes no mistakes at all. After the race when checking the race director there's no warnings for any AI, they are way way too perfect. They barely even pass each other and when they do they don't fight for position they just get right back in line immediately.
