Because you have a fixed mindset. You need a growing mindset to understant why a yoke will ultimately be better overall than a regular rounded steering wheel in most use cases. When I see the op talking about U turn or 3 point turn, my first reaction is "how often do I do such move ?", well, it is litterally 0.00001% of the distance I drive yearly.
Basically, you are taking exceptional cases and make it the rule. The reality is that in the other 99.99999% of the time, when you drive normally, the yoke will be superior : better visibility of the road, of the instrument cluster, and it also forces you to hold the yoke the "right way". How many people today are driving with one hand only on top of the steering wheel, just because they "think" it looks cool ? How many people are grabbing the top part of the steering wheel with their hands upside down (sorry, I dont know how to explain that better) and pull on the wheel having their left hand of the right side, etc; ? Well, that is dangerous, that is why the classic steering wheel IS NOT better than the yoke.
Regarding the turn signal buttons, well, again, stalks is clearly not optimal. As soon as your hands are not in the default 9-3 position (when you... turn maybe ?), well, you just cant reach them.. How can that be better than buttons that you have access to directly with your thumb, no matter the angle you are applying to the yoke ??
Finally, I would just add that you should just have a look at Formula 1 cars.. You know, they are not just going in straight lines or slightly turning in banking corners.. Yep, they are equiped with yokes, having tons of button on them, and need to turn around very sharp corners at high speed.. Apparently it works.
So, as a conclusion, I would say that what is garbage is the fact that so many people are unable to see when a tehcnology is stagnating. Today, Tesla is innovating where legacy car makers just didnt for decades.
