Hello I'm from Argentina and foremost I want to congratulate you for the great job they are doing. Sorry for my English, I am using google translator. I wanted to tell you a bug in AI, when they enter not open suction to overcome the car in front, until the braking slows the next bend. I must say that the game is in 100% of aggression. This error also occurred in rfactor 1. That's only, greetings and so continue!.
Not shure if i understand you right. You mean that AI Drivers unlikely leaving slipstream to overtake a competitor, as a human driver usually do? AI behavior is in constand development, and in every release we found some improvements. It's a well known issue and already a little better since the first beta release.
