Ok it might have been me but i did a couple of runs on Road America against Ai cars and it was really hard to come in first. It may be that i didn't sleep very well last night 👍
Edit: I do think that the Arcade mode uses different Ai driver than Career mode and it seems because they drive faster it was harder for me to keep up. That might explain it.
Yeah i noticed that too, When you go in My profile >> Opponents you can see all the drivatars that are in the game with a short description of their skills. Imo the all out fastest seems to be N.Wiswell (Nick). I raced him a couple of times in Arcade mode and that guy is pretty darn fast.
