I have a theory. Looking at the Teslafi stats most MY LR AWD (what I have) that are on new(er) versions have VIN much less than mine (1579XX). I suspect all of us who are not updating have a quite recent VIN. My theory is that this VIN is linked to a hardware change (battery pack capacity?) that they don't want exposed yet. The theory is that if we could update SW it would see whatever this update is, it would become known, and might cause people to wait for these newer VINs in places in the country where they are selling local stock with lesser VIN. Just a thought...
