It is somewhat crazy that the shift to a touch screen, which for some, is hard to use and for all, lacks tactile feedback. You can't beat a button or a dial-in in that respect or even replicate that fully on the limitations of a touchscreen.

It almost feels like there is an untapped market for after-market physical controls that can interface with the car that is begging to be tapped. Equally, shudder if somebody patented the ability to add physical controls to augment touch interfaces.
