he did add some gratuitous miles Two miles is "gratuitous"? That's a rounding error, even on my bicycle! and he exceeded the speed limit as Musk claimed Does Tesla expect drivers to adhere to posted speed limits even when prevailing speeds are much higher (as they are on I-95)? edit: CamperBob2 wrote "Apparently the reporter was averaging 81 MPH, going by an earlier comment." As far as I can tell, that figure is based on a Reddit post from yesterday (http://www.reddit.com/r/technology/comments/18c15x/tesla_ceo_elon_musk_accuses_new_york_times_of/c8dmzp9 http://www.reddit.com/r/technology/comments/18c15x/tesla_ceo...) which in turn is assuming that the times and mileage on the travel map were exact. It could be. But then again, those times could be estimates (note that 7 out of 9 time stamps appear rounded to the nearest 5 minute mark). I guess we'll know when Tesla releases the logs.

Apparently the reporter was averaging 81 MPH, going by an earlier comment. I don't know if that's true or not, but that is a very high average speed and it will have serious effects on fuel economy. To average 81 MPH in traffic, you are going to need to spend a fair amount of time north of 90 MPH. If the charging station intervals were based on expected speeds closer to 55-65 MPH, then the idea that the trip could be made at 80+ was questionable from the outset. So, yeah, there's adhering to posted speed limits for best fuel economy, there's driving with the traffic for maximum safety, and then there's full-blown Mad Max mode, which is apparently what you do when you want to make the car you're testing look bad.

  That doesn't seem very plausible. What's the other comment? Averaging 81 MPH is nearly impossible in the Northeast.

      Ah, that seems more plausible if the speed limit was 75 for that stretch.

Does Tesla expect drivers to adhere to posted speed limits even when prevailing speeds are much higher (as they are on I-95)? Expected or not, I've flown past Model Xs, doing 65 MPH myself, on the odd stretch of highway where I suspected the Tesla driver might have some 20-30 miles to go before finding a home port. If you're cruising on, erm, fumes, you'll baby your speed to increase mileage. Even in a gasoline-powered automobile, I've noted (and adapted to) highly variable range depending on driving conditions and speed, of up to 150 miles' delta per tank. Not inconsiderable, particularly if operating in areas where services are infrequent (also a possibility for conventionally fueled vehicles).
