During race in online multiplayer, everything related to my position is always off by a couple of positions. So e.g. if I'm in position 8, it treats me like I'm in position 3.
So things like:
"You are 1.2 second behind the car in front", is wrong.
Callouts for cars crashing/spinning in front, actually happens elsewhere on the track.
My actual position callouts, "Thats a podium finish" even though I finished P8.

The actual difference varies from race to race. I'm guessing it has to do with people leaving/joining not taken in to account.
I've always played servers where there first is a "Qualification" session followed by a "Race" session.

I love cc, but this unfortunately makes it unusable for online racing.
