Improving batteries is a major research area. Getting more capacity with less weight and lower cost will make electric cars more viable. I would like an electric car, but I hardly drive anyway these days. I do see more charging options around though in car parks, by the side of streets and on homes. Electric cars ought to be idea for people in cities who rarely go far, but if you live in an apartment then charging may not be easy. There should be more use of car-sharing schemes as many people only need a car now and then. There should be good public transfer to reduce that need.
