@genmaicha Screens in cars should be industrial rated for temperature range, UV exposure, etc.
Plus it's easier to swap than dealing with all the wiring for all those buttons/controls.
Additionally modern cars also now have a computer that can fail and take them out too. Or they'll share wiring with other functionality. My Subaru had nonstop issues with o2 sensors and every time they went out it took out my cruise control too. How is this okay? (I'm aware there are improvements to CAN BUS and maybe a replacement, been a long time since I looked into it)
Modern cars have over a mile of wiring to support all this. Sounds impossible doesn't it? Now imagine how many of these cars go to the junkyard too early because of a wiring short and nobody can afford the cost of labor for a mechanic to successfully pinpoint it?
My friend @SlicerDicer repaired the ECU in his original Tesla Model S because it's just a giant computer board. It wasn't even that complicated. He has backup boards he can just swap in at will
