In the name of $DEITY: WHY? I would pick without thinking the car without the child tablet attached to it, too. We will be forced to switch to this kind of stupid cars by regulation, or planned obsolescence, not by choice.

Not entirely regulation and planned obsolescence but because cost. Coding in the climate controls on the touch screen has a fixed cost that doesn't really increase with each car built. Adding multiple physical buttons, does. Even if each button costs cents to make.
