Broder's statements are much clearer than Musk's; the Tesla founder's blog post referenced image captions, quotes, and assumptions without much transparency, and Broder's is a very clear response to individual comments. There's certainly some weird numbers stuff going on here, with some of Broder's notes not matching up exactly with the data taken by Tesla, but it also seems like Musk attacked the Times article based on some assumptions he drew rather than on what's in the piece, and also that Musk is manipulating a bit of the data or at least misrepresenting it. For example, Broder did not fully charge the Model S at each stop. That's true! But Tesla's representatives told Broder specifically that he had charged the car enough, and that he could proceed comfortably to his next stop. And given that the Model S takes hours to charge, why would Broder charge it longer than necessary?
