In real life you correct it about 90% and the 'snap' does the rest...

..And that snap is also quite visible in a lot of videos/incars. Unfortunately AFAIK it's extremely hard to reproduce in a sim, in fact I cannot name any that does it well..

Quote from AndroidXP :

One thing I'm fairly certain of is that the new tyre model will have more load sensitive tyres, since that is from my understanding of tyres the only thing that would fix the issue Scawen described (too much grip on outer wheel, simply reducing grip won't fix it but would only shift at what speeds the problem occurs). By increasing the load sensitivity, the outer, loaded tyre would work less well than now, resulting in a more equal spread of how much the loaded tyres provide grip compared to the unloaded ones.

Nice post there

The interesting (and confusing) thing for me is that more load sensitivity generally means more understeer (under braking) and generally snappier behavior. I've just recently discovered the huge influence of the load sensitivity curve on my own tire model (far from LFS standards, but still something worth playing with ).
What's also interesting is that if the issue is "simply" load sensitivity, how come the whole model is being changed? I would have two ideas:
- The load sensitivity is derived internally from some the model itself, and Scawen wouldn't see it fit to change just this part of the model (plugging in a "custom" curve for the load. sens.)
- Since he started working on the model, he thought of other things to improve and the original issue led to an (unrelated) whole rewrite of the model

These are the ideas I can come up with from the information given, but I have the feeling that the information we have does not completely describe the situation. I don't think a 2 sentence brief from Scawen says enough about the whole model

The tire (tyre) model of any racing sim is _the_ single most important part of the whole application. The fact that the tire model is being worked on is just about the best possible news that can be (unless there were some other parts so underdeveloped to ruin the whole "sim" thing).. That given, it really seems some people just cannot be satisfied at the moment

No, if you ever try opening the files up and playing about you'll find it's just a simple spreadsheet style curve exactly the same as the ISI one.

Not exactly true, the RBR engine curves (the VE ones, the trq ones are just for display) only make part of the equation. Yes, there is "a curve" at effect, but the underlying engine model is still much more complex than most others.

Considering the the hardware Gt4 is on, its a Excelent job of a sim.[Remember ps2 was designed in late 90es]

A certain piece of software codenamed "RBR" ran fine on that hardware..?

LFB while on a DFP in front of a computer, mostly RFB in normal driving.
Used to experiment a bit with the "classic" rally LFB in my late Lada Samara on dirt roads - most regular "modern" cars cut the throttle when you press the brakes, so you can't get sideways with them.
That said I do occasionally feather the brakes with my left foot on longer turns when driving a bit more "spirited" - I own a Ford Focus now and it reacts very well to small brake input if I feel I'm going a bit too fast for my own good

Will be getting a G25 sometime - I wonder how "natural" it will feel to use clutch-H-shifter-RFB after doing something different for years..

Because some of us may have to choose between one or the other. It could be
money, time, focus, whatever. In my case it is a choice for our league...we cannot
expect members to buy multiple sims and get familiar with them all.

So a choice sometimes has to be made.

One of the best, most comprehensive posts I've ever read here (and by far not the only one), it made me break my long-kept silence "watching, waiting" - Well it seems it took you some time too
Opinions may and will differ - but this was well written
