So I finally got it. I finally got the (in)famous Tesla Full Self-Driving beta, otherwise known as FSD beta, v10.3.1 to be precise. This is my personal account of testing across three different days in New England, about 40 minutes north of Boston. Day One was a biblical, torrential rain; but days Two and Three were pristinely beautiful and sunny. All three days left me with the same conclusion. 

FYI: I'm putting together a video of my FSD beta test; it should be available on my YouTube channel at YouTube.com/AutonomousCarsWithMarcHoag.
