Thanks for the news update, and I'm looking forward to the new tyre physics.
I know and agree that these things take time to refine and perfect, but on the other hand, it can't come soon enough. I don't think I've touched LFS for nearly a year now, because driving around the same old tracks with the same limited physical environment doesn't attract me at all.
I hope (and trust) that the new tyre physics will be great, but by god I hope the update also includes more content (i.e. track(s)) and at least one new game feature (by features I mean things like damage, engine temperature and radiator damage, brake temp, eye candy, and so on).
I think LFS really needs it.
