Isn't the role of the VW MIB2 (as in "Modular Infotainment Baukasten") explicitly the infotainment part of the vehicle (and NOT the instrument cluster, cruise-control, etc.)?

I never had an issue with those, as their reach is isolated (or "limited" as people would say today) to the infotainment part of the car. It couldn't even take control of the climate system back when I had one.

Can't argue much about MIB3, it is just a few years old and a child of the Tesla Software-defined-car era (albeit still tries to uphold Volkswagen's DNA of strictly separating roles of all components, partly making it the mess it is...)
