We're taught to value the entire lifecycle of our work, at least in my field. For example, rushing to finish a steering maintenance on a large tanker truck could mean your friend gets his thumbs crushed under a pry bar, or it could mean hundreds of fatalities as the poor job you did caused the tanker to collide with a shopping center.
A missing cotter pin or a failed motor ground could easily injure dozens, or even kill them, on a large enough escalator.

This is exactly what I'm talking about. The vast majority of the time mechanical failure results in the vehicle coming to a stop on the shoulder without anything spectacular happening. Think about all the trailer blowouts where the only damage was to the underwear of whoever was nearby. We do things (like install cotter pins, on steering, not in tires, or not intentionally at least) to prevent those sorts of failures because there's a small chance of something spectacularly bad happening (and because downtime is $$ and if you're broken down on the side of the road the DOT vultures will turn up out of nowhere and find a reason to make your downtime even more $$).
