Again, it's just a basic understanding of how the build-out works. When you see a station open, on average, construction on that site started 46 days previously. So, what you need to look at to gauge whether it is slowing (or not) is how many sites currently in construction and new construction starts in the last month or so. As I pointed out, there has been ONE new construction start in 2016. And, as I also pointed out, this is the lowest number of sites currently being constructed (6) in the last 2+ years. Again, I am only talking about the U.S.
As someone else pointed out, these sites are fairly cheap to build (more then $150k on average though - actual cost is $150k to $500k). I can't see WHY in the world they would slow down on something that is fairly inexpensive, yet so vital to the ownership experience for Tesla owners. Take a look at the 2016 projection map, Tesla has plans to build a TON of superchargers this year. Will $8-12 million this qrtr REALLY make a lot of difference in earnings compared to significantly delaying the SupCh network? I really don't think Musk would delay the immensely needed SupCh network just to show a few million on the bottom line. The long term effect would be much greater. To the everyday car buyer (ie, people who will be buying the M3), 250 or even 500 supercharger stations across the US is not impressive. To be able to go anywhere, and feel reasonably comfortable doing it, that number needs to be in the 2000-2500 range. But, if you don't follow the supercharger threads very closely, then you probably don't get a good feel for just important EVERY SINGLE STATION is - people make tons of posts like, "I need this site for a trip I am doing in Feb" or "I need this site to be able to use my MS on a trip I take every month." So, if we are seeing these kind of comments with 60k MS's on the road in the U.S., what will it be like when there are 500,000 Tesla cars on the road (in the U.S.)?
People are GREATLY undervaluing the supercharger network. Range concerns are still the #1 reason people won't even entertain the thought of buying an EV.
