i agree with this. or when more superchargers are around/available which will happen soon enough im betting. but they need to build more superchargers quicker than they sell the cars otherwise they'll just be chasing their tail.
unless ridiculously common (plugin at walmart and at work and at tgifs) i'm not sure the availability would really drive me. right now charging seems like visiting a slow gas station, more slow gas stations wouldn't seem like much of a change. but if there were charging tethers available literally everywhere i go, then you wouldn't feel much pain at all (or need nearly as many batteries/range)
