Are you sure you haven't misread 40.4.2 with 44.2?I thought it was only me...my Y just re-installed 44.2 even though It was already on that software when I collected it last Thursday. Strange
It was just out last week so that would mean you had a day of sw release vehicle, would seem pretty unusual. The first cars that got 44.2 were on Dec.3rd according to TeslaFi..
