I'm keeping my fingers crossed for a 4-wheel-drive Tesla model for those of us who live where it snows copiously... but that price tag might be a game-changer regardless. That's going to open up a whole new demographic for them.
Gasoline cars have batteries that die in the cold too.
Which is one of the reasons you have to plug in a gas car in cold weather as well, the other being the oil freezing in the crankcase, a problem a Tesla doesn't have.
