We're getting pretty far afield from the original point of decoupling control systems from network connected infotainment systems, which doesn't necessarily eliminate backup sensors or cameras. The current everything-in-one-bucket implementation is a matter of convenience and cost savings for the manufacturers, not a hard technical requirement.

I could go on at length about the consequences of trying to play whack-a-mole with human stupidity and how that just breeds stronger idiots. There have been no significant changes to vehicle-related death statistics since the 90s when airbags were mandated, despite significant improvements to crash protection and countless here-let-me-help-you-with-that safety features that have been introduced in the last 30 years. So what do you call it when improving safety doesn't actually improve safety?
