Just dropping some settings from various well-tuned AIW files for ISI-based sims in a thread. Thought you might find it informative. I noticed a couple things I hadn't seen before e.g. AICautiousness
I know parameter settings like this don't transfer one-to-one from one game to another, since the underlying games are different, but I suspect there is still something to be learned here.
From GTR2 HQ tracks by @GTR233
AIBrakingStiffness=(0.75,0.75,0.75) // (Rear, 4WD, Front), lowering values will increase AI brake points and reduce collisions
AICautiousness=(0.75)
AIRange=(0.05) // lowering value will make AI cars closer
AIDraftStickiness=(5.0) // Increased AI speed in m/s when a car follow another one
From Automobilista default content tracks by Reiza
AIBrakingStiffness=(1.0000,1.0000,0.9000)
slowwhenpushed=0.35
AIRange=(0.1000)
AISpec=(0.0000,0.0000,1.0000,0.0000) // 4 ways to express AI speed on track, limit the acceration, max speed, their cornering speed, or their deceleration. 0.0 - 1.0
AIDraftStickiness=(3.0000) or (4.0000)
From @Speednut357 and his explorations
slowwhenpushed=0.10
AIDraftStickiness=(0.9600)
NOTE: for GTR2 and RACE 07, there are also the RaceRatio and QualRatio values controlling relative speed in the race and quali, respectively. But these are not "globally" set for basically all tracks in the whole game, but must be tuned case-by-case.
