A lot of this also comes back to asshole design, and EV's can be particularly bad for this. Switching to large touch "entertainment" displays is a major issue. With my last ICE (Honda) vehicle, it was integrated into the backup+side cameras and a few comfort/convenience features. I could still replace that with a new head unit, though only certain ones would still support the cameras.

My wife's EV (Hyundai) on the other hand, the console isn't really made in a way where it seems swappable, and even if it was there are major system functions - such as configuring charge/power settings - which can only be configured from that (or the dogshyte app that screws up often and requires a paid subscription after 3yr)
