I experimented a bit with rFactor tonight, trying an all-AI race with the AI skill and aggressiveness cranked up quite a bit. Unfortunately, that tends to end badly in the first corner… I had to reduce the aggressiveness to 75% in order for them to start the race properly, but then two more pileups 10 laps later knocked everyone else out of the race and left me alone on the track.
(Plus: bonus Ferrari vs. tire action.)
