With the touchscreen cars I've rented or driven for work I'd have loved to have a little bluetooth or serial connected control cluster that sat near to hand with basic radio and climate controls. Something I could operate by feel. Seems like there are enough bad touchscreen consoles out there to make an aftermarket kit viable but maybe I underestimate the technical challenges.

Maybe I'll just keep driving my junkers until voice control gets good.

This often means a large knob that one can turn, use as a joystick (up down left right) and push in for selection. This knob is used for navigating the majority of the console. There are some unique buttons and knobs for things like volume, climate, etc.
