When I was still noodling, there were several RTOSes that
were POSIX-certified (QNX and VxWorks, amongst others).
Of course, these ran on the higher end 32-bit MCUs, of
which dozens exist in modern cars. That medical stuff
probably conforms to IEC 62304, regardless of its
internals.</span><br style="caret-color: rgb(0, 0, 0);

<div>We know 1-2B go into smartphones, perhaps another 250M into
