Controlling steering using electric motors also helps to reduce fuel consumption and hence carbon-dioxide emissions. (Electric motors require power only when the steering wheel is turned, whereas a hydraulic pump drains power from the engine all the time.) Ford reckons 90% of its cars will have electronic steering within three years.
