Yes, hence why I said I'm not sure about enforcement mechanisms how they stack up against the aviation standard. Still, in my limited experience, projects that are ASIL x take the thing pretty seriously and they do get certifications from external bodies. Actually, I am supporting an SEooC external certification right now.

The separation most likely happens _outside_ the infotainment itself, through a gateway.
