I did a bit of AI tweaking using
@Esotic's AI Line Helper app.
The AI lines themselves were very good and very fast, Mitja did a great job there, but the limits and ai_hints.ini were not good. I remade the limits for both the GP and Piper layout, along with accompanying ai_hints.ini. Now AI happily races at 100% strength and 100% aggression on both layouts without much trouble.
While I was at it, I also remade pit lanes for both layouts, making them more in line with the fast lane, and most importantly, fixing the pit lane on Piper layout that was (mistakenly?) just copied from GP.
