My interpretation is that they do not consider the infotainment display or associated processor to be safety-critical. All of the safety-critical stuff is in one or more separate processors that stay running if the dash computer crashes.
I can see that perspective as long as the processors are segregated and the display doesn’t display any info necessary to mitigate a hazard.
The problem with a lot of software on embedded systems is that it’s easy to go down the rabbit hole and be one or two degrees away from declaring it critical. If everything is critical then nothing is
In my line of work, if it displays real time information to make safety critical decisions, it’s safety critical software
