Given the recent updated 2017 Charger roll-out map that shows 78 new SuperCharger sites coming to California and another 24 sites coming to Texas, I extrapolate that Tesla is trying for 463 new SuperCharger sites in the U.S. alone in 2017. Given that Tesla has added about 16 sites YTD, this seems like another Elon Musk alternative fact -- which might come true mid to late 2018, rather than 2017 as Tesla 'plans'. There are 249 days remaining in 2017, including holidays and weekends. 463 new sites will require 2 new adds daily, and quite likely 3 new adds daily in December, given that we are lucky to have a single added SuperCharger site in a week now. Is this realistic? Can they ramp that quickly? Certainly, earning money (perhaps enough to sustain the network independent of Tesla) with idle fees and post-400-kWhr fees incentivizes things. But, from my personal experience in the cellular phone industry, which ramped mightily in the 1990s, there is no way this Tesla 'doubling' happens in 2017.
