physical buttons are reliable, easily repairable, more accessible to people with a variety of conditions, allow you to memorize location with feel, etc. I've never met anyone who's preferred capacitive buttons over physical ones yet more and more every "smart" technology seems to be opting for them. Some have even added haptic touch-like software to them... just to regain the feeling of the thing that everyone misses…
Apart from regulation mandating that safety features work, are reliable and are easy to use (physical buttons), I think we need some new economic theory. Why is it that for products with complex spec sheets, the free market (the auto industry is arguably not a free market) does not work to provide the desired diversity? Automakers clearly have the incentive to make any control a capacitive touch surface for many many…
I sincerely hope that capacitance buttons and touchscreens are just a fad like digital speed dials from the 80s. They seemed cool, but ultmately analog dials (even if controlled by digital signals) were just better. I think physical knobs and buttons will come back for the same reason as round steering wheels. It's just the best solution to the problem.
