This is the difference between a Professional Engineer (ie. the protected term) and everyone else who calls themselves engineers. They can put their signature on a system that would then hold them criminally liable if it fails. Bridges, elevators, buildings, ski lifts etc. all require a professional engineer to sign off on them before they can be built. Maybe self driving cars need the same treatment.
