If they want to change the UI for a shifter, they should make it completely different, not make something that looks, and superficially feels the same while in actuality it's quite different. What they did is akin to wanting to have a joy-stick instead of a steering wheel, but instead of just putting in an obvious joystick, they made it look just like a steering wheel.
If you look at the picture, you're supposed to "upshift" it into Park, so you'd hit up to go from D to N, then up again to go from N to R, then up again to go from R to Park.
Which is pretty stupid, since it's just a quick shove to get it into park in every other vehicle. And even in joystick shifters, they make full use of the joystick - push IN to park (from anywhere), push UP to reverse, push DOWN to drive, push AWAY for neutral. This still leaves a pull towards you for an action - low gear, for example. The beauty of this is it's the same action to go anywhere to anywhere - if I want to go park, I push the joystick in. If I want to go from park to drive, I pull it down. If I want to reverse, just push it up. And neutral is just shove it forward away from me.
But a shifter is generally assumed that slide it away from you all the way to park it - push the button, shove all the way forward, it ends up in park.
And if you really know your car, you know which shifts don't require pushing the button - park to reverse requires it (and vice versa), reverse to neutral no (try it! most vehicles will shift from reverse to neutral without the button), but obviously, neutral to reverse requires the button. Same as neutral to drive, but some vehicles don't require drive to neutral to have the button pushed. And from drive to low gears requires the button pushed, but going from low gears to higher gears and drive, no (which requires careful shifting if your car doesn't require pushing the button to go from drive to neutral!)
