Video from AI and setup tests.
Really waiting for updated AI, current PS4 v1.14 AI is so sick, higher you set their "skills" and more they're aggressively crashing with each other's and you. Alien AI has approx 15% disaster proximity on first corner(AI pile ups, without you involved or sandwiched), weaker AI and weaker proximity on first corner accident, but weaker AI and more "braketesting" on middle of corners you have, but their awareness on your existence is better, Alien doesn't see a thing, not on sides, front or rear, it just rans thru.
Recording race against Assetto Corsa AI is bit joke, because AI speed isn't actual challenge, actual challenge is to avoid AI's stupidity and try to stay calm on his stupid moves. Below is one two lap race, but surviving AI moves toke over 100 restarts, 90% restarted on first corner, either lag/slow motion error (approx min 30% starts because slomo), rest 8% races were destroyed by AI on second lap, one race I'm remembering ending purely on my own driving error..
Over 300 starts later on Nordschleife endurance cup and hard/very hard/alien tested I can say this, use hotlap and drive alone.
