How about floor vents in the rear of cars so that passengers can have heat in the winter time, as opposed to having to wait for the front of the car to warm up before recieveing heat in the back? C'mon guys its just simply a couple of ducts, a small cable or two and a lever to open or close them. 1968 VW vans had this feature so I'm sure that 2014 Fords can figure this one out.
