My attempts at the aptly-named Trial so far:
1: Stock Senna, too slow to win and came 8th, 7th and 8th - the only other human to do better came first, everyone else was behind me (in superior cars).
2: Tuned Senna, 998 PI, came 1st, 4th and quit. I managed to clip something in race 2 that stopped me dead while in 2nd place and fought my way back up, the race leader did the same and quit, all the other humans were languishing at the back in terrible cars so I quit during race 3.
3: Same Senna, quit in the first race because I was coming 2nd to a human until an AI Regera PITed me so I missed a checkpoint. I rewound, figured I'd carry on, got knocked off course by an AI and missed another checkpoint, so I quit - at which point we had a human in the lead and I was coming 9th, ahead of one AI and the rest of the humans.
It's annoying because I feel like if I had the tuned Senna in the first try we would've won. I'll try again when I'm less likely to throw my controller through my TV.
