I agree. But I'm not convinced it's an inertia problem simply because those calculations are a basic aspect of sim vehicle dynamics that's supposed to be well understood and agreed by now. It does look like lack of inertia alright. And if a car is rotating so easily it will snap around with a small lockup in straight-line braking, ending up on the opposite side of the track, e.g. F3's, then you'd have have thought people would realise cars don't do that so easily or they'd be death traps for everyone. Forget data, it doesn't even look right - not for a full size vehicle. They're like little toys snapping this way and that. So it's a case of cornering completely with the pedals and steering is just just for straightening it out. LOL One reason some may not see it is that they're using brake and throttle together which has a tendency to "dampen" out these effects. It has always had an exaggerated effect in sims. "Throttle-brakers" are, in effect, driving a different sim car to those who don't do that. Another reason might be that they're such incorrigible fanboys that they think the physics most real racing teams import into rfPro (a different company) validates what they're driving in a game. As for data, in iRacing, for years people including some devs, ridiculed and demanded data for iRacing's supposed daft behaviour. But low and behold, despite its absence, most of that "ice racing" behaviour has gone now. In fact it's gone the other way e.g. you can take your feet off the pedals in the Skip Barber with the max oversteer setup and it stays planted. Nothing like the rF2 regional - which I'd rather drive all things considered btw. AC was supposed to be an antidote to this skittishness but it's not quite reactive enough IMO. But the best sim racer of all time, plus some of his team members think AC has great feel. So if you disagree, fine, but I wish people wouldn't imply it's because someone can only handle simcade physics. That makes no sense. I used to h&t an iRacing car on the old tire model that was widely considered undriveable that way, and did fine thanks. Doesn't mean you don't want to feel more "inertia" (and thus, immersion). All sims have strengths and weaknesses. Sometimes, I feel like a curry, other times, fish'n'chips.
