Touch with no feedback (assuming no ridges or surface coat on the icons) for controls such as turn signals and horn is pretty scary to me. Maybe one could get used to it, but I don't see why replace physical buttons and levers. It's worked forever, you don't have to "learn it" or else miss blaring in a potentially dangerous situation, maybe because you couldn't twist your finger with pinpoint accuracy and precision and the yoke was not level so very hard to visualize in your mind without looking. It's absolutely one of the things touch controls fail at and any progress and innovation won't change until at least shape-shifting surfaces become mainstream (if ever)
