Nathan, this glitch is not as it seems. The AI goes so fast only for drivers who you can't see. I play in Real, in my first career's race at Brno Miller and Fenati ran on 2:04 (3s faster than pole), I was 14th and drivers around me ran on 2:09.6xx (same time as me). Just fun!
But..there is a "but": when finally my bike was competitive and I can fight for podium the firsts two had decent lap times! 1 second slower than pole lap, exactly what happen in real life.
Nathan, just play the game, that "time lap problem" is not a real issue, we can define it like a ghost. It's a not real problem in my opinion!
Have a good day.
