Column shift master race. So much room in the Yukon you never notice it being there.

Yep.

So much cost and mechanical linkage that is unnecessary, you're still just telling the computer what gear to put the transmission in. Do it with $1 worth of backlit switches vs multiple dollars worth of bent metal, sliding components, pins, gates, etc to enforce a shift pattern and link it to the brake pedal. All of that linkage also can't collapse cleanly during a crash, decreasing the safety of the vehicle.

The only mechanical linkage I'm aware of on a modern column shifter is the parking sprag, and even that might be gone now. The reason column and console shifters are the best is that they are intuitive (pretty much the same in every vehicle) and they have mechanical feedback (you know whether you're in Park or Drive by feel). Push button and dial shifters work, but they aren't as good from a UI standpoint.
By the way, the dial shifter that Ram uses has a brake interlock (knob is 'locked' in park until the brake is pressed, might lock you out of park or rev while moving too, not sure on that). In that way, it is superior to the push button systems in that you at least have physical feedback that it isn't going to do anything.
Lucky for both of us, I can buy a car that makes sense to put into gear, and you can buy whatever you want.
