@Meza994 Meza, who said it's 100% like in the game?
And what players complained about the lack of grip? For real. Yes, people pointed out that it's easier to lose the rear, but it was quite the contrary from what I remember from Opmeer, Kiefer and iContrast videos - they all thought the handling was more realistic.
Sorry to lump iContrast with the others, it's just that he's been lowkey solid way before screamtubers exploded in the scene. If you ever dig up his old videos about racing concepts you'll notice he actually knows a thing or two about vroom vrooming.
I don't get where you took lap temps from and why you're assuming a hot track surface would conduce to less grip. Anyway, the track being the slip festival it was on the 3 free practices is in part a consequence of it being new and green (other categories and feed series were scheduled to run only after FP2, some having run today before quali and I think there's still a Porsche cup to debut there before the race) and in part for the surface characteristics of the track.
It is bumpy and coarse. The resurfacing activity also put a patina of dirt on top of it all, but being bumpy and coarse are decisive factors for varying grip levels all around the lap.
Tarmac conditions aren't exactly a guessing game. Pirelli for instance released their analysis of the track in advance - which always covers surface abrasion and other characteristics, even suggesting camber settings and fixing minimum tyre pressures. Anyway, this is deep speculation territory so I'd rather move on.
Back to the Michelin debacle, c'mon Meza. 100*0.2 equals 20 and 1m*0.2 equals 200k, but both 20 and 200k are exactly 20% of their original values! If you have a highly performant machine with enough power to easily exceed their grip limit and you SUDDENLY make it work at 100% power with only 20% of the previous threshold for power, you're risking breaking traction if you do not act upon that deficit!
How in heck does it matter how much downforce you generate when you're having or quartering or whatever the capacity for laying down power? You CANNOT bypass the tyres' limit.
Moving on, this whole debate is aimed at players playing with pads or cheap wheels fuming at how they cannot go full beans with extreme setups like they (think they) see on TV.
Patches of grass, painted lines, damp tarmac, gravel, whatever. It really doesn't matter, I was just trying to make the physics approachable as you seemed keen on pressing that these cars must had surely grown out of the tyre limits of the Michelin era with how much downforce they generate - almost as if that downforce had any way to act upon the world and translate to performance other then through the tyres. If we're finally on the same page here, then it's all good.
Same goes for the dumbed down examples of a single state for the whole grip level. Your total grip is the sum of how much grip each of the four corners of the car is producing, so you basically run that operation 4x accounting for the coefficient of grip for each tyre and the corresponding load sitting atop of it.
Have you ever visited F1 Technical? The forums, not the subreddit. I'm sure you'll love it! Also please look further into this coefficient of grip/friction and how tyres generate grip longitudinally and laterally. It's your kind of jam.
By the way, couldn't do any better than a quick search on mobile, but the best number I found for said coefficient regarding modern Pirelli tyres was 1.5 for slicks. Racing tyres have come a long way this past decades, but mostly on durability and flexibility - working range, heat cycles etc. We didn't have a earth shattering physics shattering revolution regarding the adhesion between rubber and tarmac as that is the result of those materials' characteristics.
Rubber is rubber. Downforce has nothing to do with it. Unless you mean lift and airplanes haha
