It says "mixed-criticality"
"Mixed-criticality essentially means one chip is running two pieces of software that require disparate safety levels. An example would be a single chip that controls both radio volume and electric steering controls. A failure of audio controls is annoying — while a failure of steering controls is dangerous, possibly even life-threatening."[0]
It says they're working on ISO 26262 Automotive Safety Integrity Level B (ASIL-B) which from[0] says - "medium-risk" for failures e.g. headlights or rear-camera.

- HeyLaughingBoy 2y agoDo you know if this is common in automotive? In medical devices that follow IEC62304 we usually try to physically segregate code that are at different safety classifications. [edit] after RTFM'ing I see why they do it.
