Interesting. For some reason I remember 50 miles on the paperwork on both my (new) 2016 MS and my (new) 2021 MY. I could be confused; I was still giddy even after the most recent delivery. I have since come down to earth when I realized that my $10K investment in FSD was nowhere near as satisfying as my original AP1 Mobileye version. Ah well, a small set back and certainly a first world concern. The world has bigger concerns.
