I imagine they are that expensive. Even low volume car manufacturers often "borrow" switchgear from mainstream brands to avoid the cost of making custom switches. This is why any reader fortunate enough to afford a modern Aston Martin will find the cabin filled with a lot of Mercedes switchgear, as one example. Go back farther than that and Aston were owned by Ford, which is why mid-2000s Astons are filled with very cheap feeling physical Ford controls from this era. Etc, etc. Parts sharing is critical to affordable production. Touch screens are staggeringly cheap now, as anyone with a Raspberry Pi and too much free time can attest, and fits virtually any car, as opposed to switch gear design which often requires the rest of the dash to fit with the design of the button or knob too. A screen mounting location is usually just a rectangular hole in a dash.
