Remember when a bridge collapsed in Minnesota a few years ago and everybody blamed lack of maintenance?<quoted text>
That's what happens.
If cars had the same design features as a nuke upon failure of ANY of the safety systems (steering, suspension, traction, brakes, etc.) the car would bring itself safely to a halt off the road without hitting any other vehicles or pedestrians and shut itself down.
Well the truth is that the design basis for the bridge was bumper-to-bumper fully loaded tractor trailers in all lanes, plus the bridge dead load and snow and ice load, plus a margin of safety.
Then some dumbass maintenance contractor loaded the bridge with construction materials that weighed far in excess of the design basis for the bridge. Probably never knew the dsign basis or bothered to check. Yet the bridge designer was blamed.
