The author takes a pragmatic view of EV's, questions some of the fanboys but suggests some practical possibilities. This is a Canadian story but for our friends south of the boarder, the numbers can be multiplied by 10 to give a sense of what's going on in the US market. The one point I'd make is that the number of vehicle sales quoted I think are a bit skewed as here in Ontario I think that municipal and provincial governments likely make up a significant chunk of the EV's being bought, thus they are less popular with consumers.....I think anyway.
