It is naive to assume that if a car has a simple radio+CD player with physical buttons that the user will only ever use a simple radio+CD player with physical buttons. Many people will instead use Bluetooth, an aux input, or a radio transmitter to connect their phone to the stereo. Now everything is offloaded from the car's infotainment system to a phone which is even more difficult and dangerous to use while driving.
