You keep thinking that the only places that have cold weather are in the northern MidWest.
Chicago, New York, Boston, Philadelphia, DC -- the list of places that get cold in the winter is extensive.
You also have greatly reduced range in places that require A/C in the summer, like most of the South.
The natural habitat of the Tesla S is thus mostly restricted to places like Southern California.
Or anyplace with more moderate or good weather.
Again, it's not for everyone, nor will it be mass produced like your typical SUV.
But for that two car family, in Minnesota who wants a super fast, full sized slot car that don't eat gas for the good weather...Well..
