At least they got OLED style touch screens, and for a while it looked like everything would go that way but at least in cars some are going back to physical buttons.
On that note, physical buttons are tactile and easier to navigate while driving and thus safer. You don't have to take your eyes off the road and worry about a fussy touchscreen registering your tap. You just feel around for the control and manipulate it.
The appeal of a touchscreen is that you can change the interface. It can assume a wide range of control panels, which, in a car, isn't always useful. For functions you need immediately, you can't beat a fixed physical widget.
Now, what would be interesting is a surface whose physical texture and physical controls could be dynamically changed and reconfigured. So, a flat surface becomes a series of buttons, and then maybe a rotating knob in the next. Perhaps tactile holograms. I don't think something like this could beat physical controls for reliable and lasting function either, however.
