The mod itself is great, thank you for it.
But the penalties are way too aggressive. I'm getting a three-second penalty for going a millimeter over the line, having gained nothing by that. And of course, I get a penalty for running wide into the run-off, which is a general problem with AC. In effect, I'm not so much racing the other drivers, as checking if I can keep strictly within the lines.
I think most tracks only give penalties for obvious cutting, i.e. considerably crossing the inside of a turn. Afaik the penalties are also separated from invalidating laps in practice sessions — which latter is indeed triggered by any venturing outside the track.
