The Tour de France is one of the toughest and -- in my opinion -- most exciting sporting events in the world. Aside from the occasional rest day, it's a non-stop marathon that pushes competitors and their carbon bicycles to the limit. Lung-busting mountain climbs are punctuated with deadly descents and hard-fought sprints. Only the fittest, smartest and luckiest athletes stand a chance of winning the tour's ultimate prize: the yellow jersey. With this year's race in full swing, I recently decided to try the official video game.

As we pulled back into the showroom (or whatever Texas' insane dealership protection laws demand Tesla call the places it's not allowed to sell or service vehicles), I told the rep that I was driving to Austin soon; Autopilot would be just the thing for the long stretches of empty road out on I-10 and TX-71. Without missing a beat, she offered me a loaner Model S. Ars has officially driven a Model S with autopilot before, but only under controlled circumstances. The Austin trip would let me take the car out for nearly four hundred miles of driving in a big mix of traffic scenarios. Plus, I'd get to log more cockpit time in a Tesla. Of course I said yes.
