I'm a big fan of the Commander knob on my Mazda (despite absolutely everything else about their infotainment being hot garbage). It's so easy to use without being distracted, more so even than physical buttons. But unfortunately, it seems like Android Auto is going more and more away from supporting non-touchscreen inputs. First they added forced "look at the road" breaks when you were scrolling a large list, which actually made it more dangerous when scrolling with the knob in a Mazda since it would just take longer. And their new layout is pretty terrible for a rotary input as it has no clear tab flow.
