Yeah, missing a 30 day announcement was stupid, but also very Tesla like. It's just the way Elon rolls.
However have people stopped to consider what the vehicle landscape will be like 2 years from now? Most of the supercharger network will have been built out. Did you see the news announcements that gasoline consumption in CALIFORNIA had dropped 2% in January/February? Can you imagine how things will be vastly different 2 years from now? I have been trying to imagine it and I"m not quite there yet. Let's see, we'll start to see complaints from gas station franchisees that for the first time ever their volume is dropping. Slowly, ever so slowly, it will percolate into people's minds that Teslas are no compromise electric cars. There has GOT to be a business case for some other business (other than directly competing with Tesla) that can piggyback onto what Tesla is doing.
