I'm not sure if "the breaks on the train failed" and "the train's ai suddenly decided to start running in reverse" would get the same reception even if the result was the same.
Yet aircraft autopilot fails, pilot error, and mechanical error seem to all get the same attention. That might be because the pilots are also at fault for autopilot issues, or it could be autopilot used to be really really dumb so there was a lot of stories that autopilot flying into a mountain etc to prep people with how dumb it was or it could be something else.
If that makes sense?
