Good point, you are totally right. I don't drive a car which uses the infotainment system for mission-critical functionality. I've actually run it without the infotainment system in the car at all. Tesla's would effectively be bricked without the head unit functioning.
Ford and the rest of the reputable OEMs know a thing or two about flash degradation though. It was actually a huge sticking point in one of my infotainment projects with them. So I don't expect all the OEMs to make the same bone-headed mistakes Tesla has
If you are allowed to share, what is the typical OEM specified lifetime for the infotainment flash part? I guessed 10 years in my original comment, but that was a gut instinct and completely uninformed.

Your guess would be nearly as good as mine, I worked as a vendor and never actually had to abide by the requirements the integrators over at the OEMs had to stick to.
Usually when talking with them they would throw around "lifetime of the vehicle" requirements. For typical OEMs I think they consider that 15-20 years. Tesla, probably 10 lol!
Though, in reality, if you baby your flash to last 15-20 years. You've probably designed it in a way that it has a chance to live a whole lot longer.
Recent non-tesla rentals I've driven have definitely had functionality that could only be accessed through the touch-screen. e.g. a Chrysler my mom rented a couple weeks ago had just temperature and fan control on knobs; everything else for climate was touch-screen only. What happens when the eMMC gives up the ghost in this car? I don't know, but I suspect you won't be able to e.g. manually put the defogger on...
