This is realy good news, I can see alot of things changing just with this one re-write.
Maybe my lap times won't looks so bad when compared to others now, I drive like I do in real life, so I never push hard enough for LFS's current tyre model. When the tyre grip drops I'll still be driving the same pace I bet, but it'll be realy close to the limmits of the tyres then.
One thing I realy hope changes is how the FWD cars react to left foot braking, right now they don't oversteer enough, it's like driving a car with only 50hp. I think that has to do with the tyres gripping too much in the rear, instead of slidding free they just drag the speed down.
As for left foot braking in RWD cars, it does what it should, but I think it does it too well, and again I think thats the tyres.
It's the same as doing a brake stand, the car shoulden't move forward but the rear seems to still push enough to slide the front tyres. I've burned up a set of tires doing a brake stand in the car park, and I ended up halfway across it, when I shoulden't have been moving at all.
