Is the joke that the news would rather report on the bicycle accident in this case and not the collapse of civilization?
I can barely tell what you're going for here, I feel like you couldn't have picked two worse examples. Road deaths are an everyday occurrence that we've all just accepted as normal so those barely make the news, and bicycles get even less attention than cars. And the "collapse of civilization" is the kind of thing people are shouting about literally every day and it's always an exaggeration and pure opinion.
Complainer: These editors can't judge the relative important of a bicycle accident and the collapse of civilization!
Editor: Not true. We know exactly which one is the better story.
