It's easy to portray it as arrogance, but in manufacturing, you run into small problems and ambiguities all the time.

By analogy to software engineering, do your bosses or clients give you water-tight, formal specs for the software you need to build? If they could do that, they wouldn't be needing you in the first place.

We zero in on situations like that and pretend that it's the worker's fault for making the wrong call, but we ignore that if they didn't make the right calls a thousand times before, nothing would ever get done.

In this case, if pedal cover is a friction fit and can slide off and get jammed in between panels, this doesn't sound like an assembly mistake but a pretty major design error, right? Your designs should be resilient. What if the owner sprays WD-40 on a squeaky pedal and the cover slides off?

Exactly - especially in a TRUCK of all things. The pedal area should be expected to get getting all kinds of crud and crap in it and be cleaned regularly and be extra durable.
