The last 3 turns and circular turn 2 on George V offer a little room to pass. Anywhere else, imo, you just have to rely on the fact that the AI is gonna mess up at some point. [admittedly, I've never attempted a 150pt race there]
Citta D'Aria offers lots of room to overtake - but by far my fav spots are the downhill tightening right hander near the beginning of the lap, and the heavy braking zone as you go under the arch and enter the chicane nearing the end of the lap.
