The AEC standards aren't enforced by anything and are mostly just promises that chip manufacturers make (the AEC itself is a private entity). Specifically, that any given chip will still be available in 15 years and that it'll operate fine within certain temperature ranges.
If some part claims to be AEC compliant it's basically just the manufacturer saying so. There's no independent body or even standardized tests to prove a part adheres to any given AEC document. Their own docs state as much:
AEC Certification
Note that there are no "certifications" for AEC-Q100 qualification and there
is no certification board run by AEC to qualify parts. Each supplier
performs their qualification to AEC standards, considers customer
requirements and submits the data to the user to verify compliance to Q100
In other words, it would be up to any given car manufacturer to verify the claims of any chip vendor using their own testing methods. Since they're going to have to do that anyway, slapping AEC-(whatever) on a product doesn't mean much.
If you test your part in similar conditions and make some availability promises you too can slap an AEC-Q100 label on to your chip!
