I don't think you're wrong, but would add that there's a lot of physical engineering needed to put such a big screen in, you can't just shoehorn it into an existing dashboard. I've recounted before that Ford has the layout of their individual buttons allocated 5 years before production starts. That's why most manufacturers still have screens that are 1/4 the size, they haven't figured out where/how to move the buttons. They can't move them onto the screen, because they're all supplied as units from third parties.In 2012 Tesla came up with the large 17 inch touch screen monitor in the car. At that time that was expensive. Today the cost of automobile grade touch screen at that size is insignificant and of course users love it. Legacy makers, as far as I know, could not replicate it yet. Procuring the monitor and sticking it in is easy. Having an operating system and have all their vendors provide their output data seem to be too difficult mysteriously. It does not seem that difficult. Operating systems can be created by adapting freeware just like Tesla did. Google likely would even pay them to do it in exchange for a small real estate on the screen for ads. The vendors would not need to rewrite their software only modifying the output to go instead to their own separate display. This takes several years. But that is just the software part. Having 50 control systems provided by the separate vendors are more expensive than having one slightly higher performance control system. (Note: This is my impression with 0 expertise. If I am wrong just gently correct it instead of piling up on me.)
