Who uses a column mounted shifter these days? Most full-size pickup truck that don't have a rotary knob shifter or manual until maybe recently. As for developing entirely new mind-muscle ocnnection/muscle memory, that's literally true with any change in controls. From experience, it takes a week at most, and you will find yourself trying to shift your older vehicle with a rotary fan switch in the same place after you have been driving the vehicle with the rotary knob. I drove a rental Ram with the rotary shifter in 2015 after my 08 Grand Cherokee got T-boned, for three weeks, and that's exactly how it went down. Still, THE ONLY difference between the knob and the lever is literally the knob and the lever, unless you're used to a car console shifter, then it's just a 90 degree directional change. The sequence is exactly the same, and the PRND is still right there in the "window" in the steering wheel.
