I can't drive because of my eyes, but your argument is backwards, physical buttons can have different sizes and textures, so the Ford Fiesta has a smooth round button for the radio, I can't miss it because it looks and it feels different and it is placed in the center, then switching station you press on it's left/right edge so the driver can do it directly without looking at the button or at any display. I am not saying you should remove th3 touchscreen but keep the most important and most used buttons on the wheel or on the center dashboard as physical buttons and keep the important displays like speed, LEDs for the lights and the important systems in the dashboard.
