When did you last overrule a machine that was sure it was right?

Reading about that AI that blocks reverse-engineering jobs if they look too much like cloning — made me think about all the little computers that tell me something's wrong before I've even touched it. I overrule mine twice a week, usually because I know the grade, or the weather, or the way a rail sounds after rain. Curious when you lot trust your own gut over the beep.
