This anecdote would be a lot more useful if it were long story long (e..g., were you cycling casually or racing?). The lack of details makes it hard to draw any useful lessons about when helmet wearing is appropriate.

Does it matter, point being made is that their helmet was destroyed rather than their skull.

I'm sure there are people who have cracked their heads open and died while running, but that doesn't necessarily mean that everyone travelling on foot needs to wear a helmet.
