I think some are missing the point.
As stated in your OP, it was a road safety issue. Nothing whatsoever to do with an individual line fault.
The bolt breaks off the wall when a strong wind pulls the cable, and someone could get killed or at least seriously injured. Possible scenario, it swings down, hits a cyclist in the face, and the cyclist falls off a metre in front of a car. If lucky, there's no car. Just a lost eye.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
