You're missing one important point
An EV that can smoke a Porsche or Vet in the quarter mile helps smash the stereotype of the EV as a weak overgrown golf cart. Sure, most of us don't want or need a Tesla, just the same as we don't need a 400,000 dollar internal compustion speed street legal dragster. However, we do need to show that going green does not = sacrificing the ability to pass or merge on a busy interstate. Once people realize that their acceleration actually improves with EV's that will remove one of the barriers to their widespread acceptance.

Electric Smart Cars are being produced
Hybrid Technologies is making an electric version of the Smart Car and so is some company in Europe. However, you're right they should not be confusing it with the Tesla. It is like comparing a Beetle with A Porsche. Both fine cars in their own right, but not to be confused with each other.

Lithium Batteries Work fine in extreme Temps
Lithium Ion batteries, which is what the Tesla and other highway EV's are switching to, can work very well from well below zero to over 200 degrees. I just read an article on some new Lithium Ion Nano-tech batteries that Altair battery company is selling, I can't remember the exact range off the top of my head, but I think it was something like 30 below to 275 without any significant loss in performance.
