You've got the motive back to front.

yah, let’s get rid of these cheap, easily manufactured and implemented dials and knobs

In modern cars those buttons are an input to a body computer which then sends commands over the vehicle data bus to another module that performs the appropriate function. The touchscreen option is much cheaper once you have more than a few buttons to deal with.

Buttons have different physical shapes, the little decal for the button on each one has to be printed and put on top, each one needs to be connected to power, each one needs to be slotted into the dash somewhere , each one needs to be backlit so you can use it at night, and the signal for each one has to be routed somewhere through increasingly bulky harnesses, etc etc.

A touchscreen sits on the vehicle data bus and with a bit of software, sends whatever command is needed.

Is it a great user experience to press fiddly buttons on a touchscreen while driving down a bumpy road? Fuck no. But it is definitely cheaper and less complicated for the manufacturer.

A touch screen is more expensive than an injection molded plastic knob, even if the actual interfacing of the controls is easier.

I take the point that it’s simpler to integrate with how many buttons, dials and controls newer cars have, but I think the proliferation of those bits is part of the same issue. A lot of stuff is being added not because people find use in these things but because companies feel they need to add them to appear like they’re tech forward.
