Random data point for anyone who actually cares.... I drove my 85 across the country from Raleigh NC to Palo Alto, and until I crossed the NV/CA state line, we saw roughly 10 other Model S cars *combined* at all supercharging stations. Then I arrived in California and there were cars everywhere. We didn't have to actually wait in line at any point, but at Gilroy, Atascadero, and Tejon Ranch there was nearly 100% occupancy.
Yeah, this just goes to show the US market for Tesla's - it really is overly concentrated in CA. And yet Germany has more superchargers and much, much, much fewer cars. Sorry, I don't agree with that strategy.
