The major WTF moment for me was this: > I was given battery-conservation advice at that time (turn off the cruise control; alternately slow down and speed up to take advantage of regenerative braking) Someone failed at basic thermodynamics. Converting electricity to mechanical and back to electricity causes a terrible loss in power.

Point 4 of this article suggests that accelerating in short bursts with long coasts in between works best for gas-powered cars. I can see how turning off cruise control could be more efficient in this case too, although I agree braking would be silly. http://www.mrmoneymustache.com/2011/07/26/hypermiling-expert...

No it doesn't. What the article says is to keep your velocity constant = zero acceleration by coasting and giving gas in short spurts. But it's entirely possible that journalists don't know the difference between "giving gas" and "accelerating the car."

My summary: 1) We need more EV infrastructure, a point that seems to be getting lost and that I think should have been the thesis of the original article. 2) Broder was irresponsible for not taking seriously enough what the car was telling him and trusting too much the judgment of people 3,000 miles away. 3) Musk is on the defensive and perhaps overreacting because he feels he's doing good in the world and has produc…

I put a graph together showing all the points/counterpoints and here's what I'm left with. - not charging past 90% at the 1st station is defensible. Especially if Tesla warns it will shorten the battery's life. - It'd be better if Tesla's software took temperature into account when estimating mileage range. - Broder is being ridiculous about the cruise control and his speed estimates, and the temperature. He has part…

"reads like Broder was trying to stack the deck" I disagree. I think Broder is doing what a lot of journalists do and has accentuated the overall negative experience to create a better narrative. In spite of the poor communication and slight exaggeration, I don't feel like there was malice or a great deal of intent on Broder's behalf. He generally had a poor experience. The errors in his story do not negate that, and…

> Broder should have just presented the facts and let us interpret them.

Fixed. A journalist's job is to present the facts as fairly and accurately as possible, not to massage (and sometimes distort) the facts into a narrative that triggers an emotional reaction. If anything, I expect the CEO of a company to bend the facts into a story, but I expect the journalist covering that company to unbend those facts, not to bend them the other way.

Next time a journalist does a drive test, Musk should record all the telephonic conversations.

Depend on where you live it might be illegal to do so.

"This call may be recorded for quality and training purposes."

Broder went in with a preconceived notion, and did everything in his power to make that notion come true.

I think that's pretty much what "stacking the deck" means.
