Old Guys Rule
There are two battery developments being worked on - really, really fast charging, and batteries that won't self-destruct if shorted. One other issue is range, once they can increase power density and lighten the batteries you'll see many more electrics. Maybe then economies of scale will bring the prices down to where they should be. The only other problem is there are not enough charging stations. Even the Superchargers are a joke, because they can only accommodate a very small amount of vehicles at a time.
