Another solution is to not make every make and model have a completely custom dashboard interface. The physical interface for turn signals is completely standardized. The physical interface for windshield wipers is about 95% standardized (I wish we would finally decide on if the short bar or the long long bar indicates frequency of activation or delay between activations). The physical interface for the radio is mostly standardized, at least the icons on the buttons are well defined and understood. It just gets worse from there. The climate controls look standardized, and often have well-established icons and coloring, but not standard positioning. Then again, even things that are standardized, people can't fully grok: how many people know how to find out which side of the vehicle the gas tank is on while sitting in the driver's seat? It's so goofy, the Mini I drive regularly is infuriating because the touchscreen has a paddle/joy-knob in the center console for navigation, and you turn it COUNTERCLOCKWISE to move "forward" and "down" through menus/option lists.
