It's worth pointing out that compared to ICE, electric engines are much more efficient with city-style start-stop driving. When you're stopped with an ICE, it's still using fuel to keep the engine idling. When you're stopped with an electric car on a flat surface, the motor isn't using any energy at all. The only energy you're using in the electric car is the power for the radio and any climate control. Regenerative breaking also helps the electric car, because it recaptures some of the energy lost in accelerating the car.
