Today I have been doing some offline racing against the AI using the GT3 World mod. I had two fantastic races at Silverstone GP track with me finishing 3rd in one race and 8th in the next. The AI seem to be very clever in Rfactor2. They block, they attempt really smart moves on you and most of all they also make mistakes. Rfactor 2 is superb for offline AI racing even using mods. It can only get better folks. ps, they don't cheat either.
