Electric cars are not a real good idea. Gas taxes help pay to maintain roadways and bridges. I f people quit buying gas, Uncle Sam will have to find a new wayto recoup it's loss. And it will probably be in the form of some new tax. Then those of us who drive the old gas guzzlers will probably be hit twice with taxes. Just my thought.
Also, most electric companies are still using steam turbines that are generated by fossil fuel. So until all of America is using nuclear power...your still contributing to the problem of fossil fuel. And if you are on nuclear power... then your contributing to nuclear waste.
I think there is no quick and easy answer... but it would be cool to build your own electric car. LOL!
