I am actually also enjoying the critical thinking about UX that is stemming from this design.

I'm starting to feel that full software modifiable screens are not the "new age" of in-car experience, but a v.01 of highly customizable, highly complicated settings control; a lazy first implementation. What we are seeing with your design is more of the refinement of the concept. So, kudos to you!

I concur with many people that this might still not completely cut for "eyes-free" usage which you need while driving a car. But for a lot of applications, it's a way more premium/refined interface. I'd limit the number of options on the main menu to 5 and already you've reduced the number of buttons from 10 to one knob.

On the note of just using the haptic feedback: did you compare things to the surface dial? I really expected that to gain more "mainstream" traction, but it seems to have fizzled out.
