Well, there's a difference between human error and pilot error. If the mechanic puts the wrong bolt in the windshield and it blows out at altitude and sucks out the co-pilot (this actually happened once), it's human error.
If Volvo programs the car wrong and it runs over a kid, it's still human error.
I don't care if they attribute it to human error - I just want to make sure I'm not going to be held responsible if I have no control over the situation.
Let's not forget that shortly after HAL started abdicating his responsibilities, Dave took him apart and left him drifting around Saturn.
