Just centralizing pollution, horrid efficiency (fossil base to movement) and further stress on power grid. An electrical car is tolerable as soon as it's operated FULLY on renewable sources, e.g. the sun AND has an acceptable range (600km at 140km/h == 86 m/h).
Has been debunked already. Even when operated on 100% coal power, the Model S produces 1/2 the pollution of a small economy gasoline car.
