Older cars and other models are this way, but not the 2012+ Ford Focus, or the C-Max for example. They have two individual motors which are calibrated separately for each wiper arm, and they also know enough to detect when they are out of position generally (e.x. if you lift both of them to clear the windshield then set them down backwards the car will cycle the wipers to park them properly and won't leave them the wrong way around).
