The Automotive Safety Standards Map: Beyond ISO 26262

A modern car can cause the same accident four different ways. Only one of them is a malfunction. Lane centering steers into the next lane. Same severity, same exposure, same controllability. One hazard. Now ask why. A solder joint opened. Or the camera worked perfectly and lost the markings in low sun. Or someone forged a steering frame on the bus. Or the model met a road marking that was never in its training data. ISO 26262 owns the first one, and it says so itself. The other three each got a document: ISO 21448, ISO/SAE 21434, ISO/PAS 8800. The hard part is not learning four standards. It is that one item definition and one hazard list have to feed four arguments that must not contradict each other.
