> A low-distraction interface is going to be more expensive to develop and manufacture than a touchscreen that can be largely assembled from commodity parts and some software. That seems bizarrely counter-intuitive as a more-or-less standardized low-distraction interface already exists for car radios. Okay, sure, you add the touch screen so you can do GPS and stuff, but is it really that hard to wire up a pre-existing car radio knob and buttons to an Android device along with some software to map twisting the knob to adjusting the audio volume and so on? It just baffles me how little apparent attention was given to this sort of thing. I wonder if these people are dogfooding.
