@ValentinGoBrrThis seems to be another issue that can also be observed at any time.
The problem that has the most impact is the sudden AI drop in performance. They will get within 5 seconds of your pace and suddenly they are 2 minutes + behind you. It happens at random at any location at any stage.
The issue above have an outstanding impact on overall enjoyment, enough to spoil all the reason to compete in career.
I have also observed the AI being too slow on the fast sections of Estonia and the overall inconsistency of them throughout the different kinds of sections. This, for instance, is not related to the most glaring AI drop off issue, although is desired to be also looked at the high priority for the single player experience.
