I bet the given minimum pressure is probably always above the grip optimum and is only given for safety reasons,
A couple of years back when Pirelli raised the min. pressures in F1 because of tire failures, the teams started to heat up their wheel rims for the checks. Just one example. These days whenever you see a tire failure, in any racing other then maybe Nascar, the reason for it majority of the time is the team running too low of a pressure in order to gain a grip advantage TK
......and that makes it a hard sell!!! ....heck, the next thing you'll be telling us is no street cars!!! Haha!!
Asseto Corsa 2 already exists whit the awesome work of some modders ,they have trnasformed the sim completely,rain,wipers,shaders etc etc.
At this point neither AC2 nor RF3 are planned. At least to my knowledge. AC2 would make sense from technical point if they implement all these features and advancements from ACC like physics, weather, night, Unreal engine... But it would be huge task and they would have to relicence all content probably. The question is if devs are interested in it. But why rf3? What would be the advantage of it over rf2? Putting new version number doesn't make software better. Devs are still developing rf2 and it seems they don't intend to stop. Btw I wonder if any developer in the future will create something moddable like AC or RF2.
Why would kunos stick to UE? That would be suicide The window for a decision on rF3 was when S397 took over, now it's a bit too late for that
In my opinion it's one big question mark what Kunos will do next. Stefano was big person behind AC and ACC. Now he is gone for his own projects and he probably won't go back to Kunos and start to work with another racing game.... We only can wait and see what happens with Kunos.
