Re: the UBS analyst question - I thought this was a totally fair response by Elon. In his previous question, the UBS guy asked Elon where their battery costs would be by the time the Model 3 launches, and Elon said he felt was proprietary.<p>Then the guy basically asks the EXACT same thing, but rather than asking for the final price, he asked for the pace of reduction (CAGR) in price, over a given amount of time (until the Gigafactory is open, and once it is online)... which would allow him to calculate cost&#x2F;kwh when Model 3 launches.<p>Musk politely answered a whole series of questions from this and other analysts, only cutting them off if they asked something stupid - like this guy. You&#x27;re not gonna trick Elon Musk into giving you more data by asking the question a different way.
