Those batteries going dead in that weather is a huge concern. Might cause someones death. You have to think about something. First, extreme temps affect a batteries ability to keep a charge. Hot or cold. Second, unlike a internal combustion powered vehicle, which used wasted energy to produce heat, an electric car has to use battery power to do the same. So sitting in that cold is a perfect recipe for problems.... IMO, electric powered cars are not ready for prime time...no matter what they want you to believe...
