You are clearly missing the point. Have you driven an S or X yet with the current shifting arrangement?
I've driven cars with 3 on the tree, floor shifters, push button, shifters, motorcycles where you have to twist the left grip to shift as well as actuate the cluteh, left had drive, right hand drive, motorcycles with reversed shifting patterns, cyclical shifting patterns, motorcycles with gear shifts on the right and left, hand shift motorcycles, twist grip throttles on the left, backhoes, combines, bulldozers, dump trucks, semis, hovercraft, snowmobiles, jetskis, all manner of boats and aircraft. Probably forgot some vehicles and control systems I've worked with along the way.
One thing almost ALL those other vehicles have in common is that you can pretty much operate the control for going forward or reverse (if they have one) without looking at and pretty much all by tactile feedback. The buttons on the S/X are totally flush with the surrounding console. At least with a pushbutton shifter on old cars, it was like selecting whatever jam you had preset on the AM radio. You could do it without looking AND it was fairly responsive.
The yoke and lack of stalks is about the only regret I have about buying my S. Well, that and the typical shitty quality control from Tesla where I had to wait a month after getting my car so they could fix something that if I continued to drive it, would have really screwed up the car even worse. Imagine if when you open the driver's door it impinged on the front fender to the point it was bending the fender and removing the paint from the door and fender and trying to bend both pieces. Last thing you want is Tesla doing a bunch of paintwork on your car and crushing the value of it before you even drive it.
There was clearly not enough thought put into the controls considering true FSD is pretty much Elon's pipe dream at the moment.
