Noticed a significant shortcoming in the game last night. I tried the M2 CS time trial around Nordschleife, and on Get Real, the car was undriveable, at least with a controller. It was very prone to getting into unrecoverable slides. I played around with deliberately provoking a slide then countersteering, and even though I was anticipating and expecting the slide, and instantly countersteering, there was no bringing the slides back. I tried on Amateur instead, which sets Stability to Low (vs Off with Get Real) and the car was fine.
Now, in AC EVO, even without any artificial assists, you get ABS, TC and Stability with this car, and can adjust the strength of all 3 individually, because the real car has all 3. What RaceRoom really needs to is to bring Stability to the same level as ABS and TC, i.e. Get Real should give you factory stability, just like it gives you factory ABS and TC. The car is extremely easy to drive in AC EVO using only the factory driving aids, which is why the undriveability of it in RaceRoom immediately got me looking for the reason for the difference.
For anyone who hasn't seen it, there's a good video here where Ben Collins (former Stig on Top Gear) talks to GamerMuscle, and they are in agreement about how fake these unrecoverable slides are in "sims" (I've never personally had an unrecoverable slide with a real car in my entire life):
