Porto Kora is easy to lap the AI because some of them can stay stuck on the walls near the first bump (On the left side) after the long right turn from the starting grid and also on the last U turn before the starting grid some will ram into the walls either inside or outside of the turn. So yeah, lapping the AI is pretty easy, in any speed class. I wouldn't know about Staten Park though, I have not played it enough for this to happen to me (Although I mostly play in Phantom and it may be impossible to lap them at that speed.)
