I think traditional car manufacturers just don't advance the state of the art in screens and other in other in-car electronics at a pace fast enough. They are content with shitty 7 inch screens with faded colors, since their supplier told them this is the best that can be done. You need someone like tesla to force screen suppliers to catch up to the best screens, do the required testing and make the best screens capable of withstanding heat and shock. It's the same with the concept of an electric car and the concept of self driving.
