I had sworn I wouldn't use pilot assist, but it just saved my behind and got me a bronze medal in a rapier time trial on Sol 2 (I was a staggering four seconds short without PA, after several attempts). Even on lower speed classes I spend most of my time slamming into or scraping against walls on that damn track - even with the most maneuovrable craft.
I'm finally starting to get the hang of Chenghou Project (still making contact with the wall on that first sharp corner more often than not though), so now Sol 2 is really the only track I hate . Well, that and to some extent Sebenco Climb in races, as the AI - even on novice - seems to handle that track unusually well. I actually have an easier time on Sol 2 when I'm up against them - despite all the wall scraping and slamming .
