To some extent, the Autocalibration at "2" with the current build, seemingly gives a hint of that.
Not the prep time, but if you bin it in the race, I don't know why, unless I go back to the splash screen and re-start the "practice 90min / quali / race" sequence, the AI will simply go crazy on any 're-start race' (even from the garage).
Note: 992 Cup around Silverstone was 100% organic with that change... zero ramming after the long practice and quali. Quite the contrary, they would show show up in one mirror, try the lunge, but with measure and, equally, in the tightest corners, they would leave space if I got to the corner with my nose deep enough for him to have to leave space. Quite remarkable experience.
Specially when they would do it and then kept it straight and forced me to leave space in the outside, exiting the corner, tighter and slower.
