They're talking about not supporting XWayland, not Wayland proper. Given this -- if Toyota doesn't want to run "legacy, unmaintained" X11 in their cars, then.... they don't have to, they can just move to Wayland, which will work, and NVidia supports Wayland just fine -- and they don't have to worry about X11 at all anymore? So, everything would be fine? I'm not sure what point you're making here...
