Tesla's map is just a hazy vision of what they hope might come. The locations and timelines are completely in dreamland.
Supercharge.info only puts dots up when conclusive proof is found for the supercharger. In this case though 'proof' was mistaken, so the dot should really be taken down.
Ok, it seems like there is the "hazy vision" of Tesla maps, the "conclusive proof" on Supercharge.info, and then ongoing contstruction that isn't listed anywhere. I work in Princeton, NJ and several people have told me about the new Tesla dealership going in behind the Porsche dealer off Route 1. You can see the white building with red accents but there isn't any info about it. I thought it would show up as a destination charger on Tesla's map.
