or... when the batteries can maintain full charge in lower temperatures such as we experience up here in the North. BTW, a lot of the USA and Europe have the same climatic conditions as Canada. This is a situation that is about to "raise its ugly head". Another less discussed issue is where the power is going to come from to charge all these vehicles. Some quick googling tells me that there are presently 1.2 billion cars on the road in the world presently. Can you imagine if just California converted 50% of their cars to electric what an enormous strain it would put on their electrical grid!! They can't keep up with their requirements now, let alone add to the electrical demand. Also, half the energy consumption in California is fueled by natural gas so there goes the "green gains". As well, supplies of Cobalt and lithium, the key components of the most efficient batteries presently available are getting harder to find (read more expensive) so I don't see batteries getting cheaper any time soon. Bottom line, look at how long we have been trying to refine the electric car. 1st ones showed up in the early 1900's and we still haven't solved the battery life/ range problem. We even put a man on the moon in between and almost blew up the world but... no solution to this problem yet..
