Alex Roy and his co-pilots recently made two historic coast to coast trips - California to New York -  in his brand new Model S. Their mission: Measure the efficiency and safety of the Tesla FSD system. How close was Tesla to mastering full autonomy? Roy and Team use two key metrics. The first is the total number of disengagements – whether voluntary or involuntary. The second: How quickly could the system recover after a disengagement?  Roy, who previously set the Electric Car Cannonball record in his Tesla, has now turned his focus to autonomous driving. His central question: How soon will cars be able to drive themselves coast to coast allowing us to take a nap in the back seat?  I first met Alex Roy in 2018 at a private industry event south of Munich. He's one of a kind - colorful, smart and professional. You will enjoy his vivid first-hand account of the cannonball runs, both the triumphs and  the reversals - like the time the team encountered a good old-fashioned midwestern thunderstorm in Indiana. How exactly did The Model S and the FSD system respond to that crush of water? Alex Roy, partner, New Industry Venture Capital on the Driving With Dunne podcast.
