Citroen went one step further on the protoype model SM. They did away with the steering wheel altogether and wanted to use a joystick like contraption in the center. After crashing the prototype they added a steering wheel. This is the reason that that vehicle tends to behave terribly when you make a quick course correction at highway speeds: the steering is non-progessive and you'll get way more boost than you expect. That takes some getting used to. One of the star football players in NL almost lost his life in the Schiphol tunnel that way. Details matter, and settled user interfaces should not change unless you have an extremely good reason.
