Electric Cars are a terrible idea to mass produce.
They are ecologic disasters. A thousand pounds of toxic waste that has to be replaced every 3~5 years in each vehicle. Preferred to be powered by either Coal/Oil Electric plants, or Nuclear Power. Of the three Nuclear Power is "Greener" but produces a lot of toxic waste. Solar does not currently produce enough energy in their life time to warrant their manufacturing. Wind does not produce a lot of energy and requires vast areas of open space.
If Electric cars would be adopted by the majority of people, we would have a HUGE waste problem.
Best alternative I have heard is Hydrogen powered cars, but they require a rare mineral as a catalyst.
