Since this rotary gear selector knob is in fact an electric switch, it would be quite easy to come up with an aftermarket center console shifter that would simply plug into the existing rotary knob harness. I think the benefit of some extra space in the center doesn't outweigh a traditional shifter where most of us rest our hand while driving. In case this idea sells in the future I should hurry up and patent this
