Yeah, so I played all night with the same issue online. This was my first real attempt at online play since they introduced credits and XP, and I still don't get it. I don't play with any assists offline, and the game behaves nothing offline like it does online for me. I can take the Indy track at full throttle on most turns offline. Online I'll just go into a complete spinout at 200mph. Again, I don't use any assists offline, not ABS, TC, or anything else. Doesn't make sense to me. Seems like it's this way for other people too because there's constant pileups in most races.
