Good to see that you're back at the tyre physics with some new motivation by the looks of it! Very much looking forward to see what you come up with in that regard. No doubt having the tyre physics done will be a great step in the right direction and LFS will probably be moving faster and better towards a finished product at that point
Although i've got an issue that started in P3. With my G27, the shifter mapping keeps resetting every time i join the track, and it's in some weird config where 1st shifter position is 2nd gear and two of the shifter positions are 4th gear and so on. I try to change this but it keeps going back every time, which gets annoying.
