Somebody call the Lockpicking Lawyer to shove a paperclip in these "security standards". They're flimsy attempts to excuse still doing something that's a bad idea (programming safety critical software in respectively C and C++) by promising to try harder to achieve the impossible standards needed by humans programming these languages.

And I do mean flimsy. Here's a fun example from a random copy of the AUTOSAR guidelines I found online labelled 17-03. AUTOSAR says if I have two 8-bit signed integers and I add them, that might overflow which is bad. So, what if I simply check that they're both less than 100, no more overflow? "Correct" says the AUTOSAR guide this is apparently OK.

Huh. Signed 8-bit integer. 99 + 99 = -58. This is probably not what the person who purchased your car thought the answer was, I hope whatever accident you just caused isn't fatal.
