I think this is a recent development and it is mostly older people who would previously not cycle as much anymore, but now drive e-bikes and so are going a lot faster while being physically more fragile. I think they were mostly one sided incidents (them driving into stuff or slipping).

For those people, I’d indeed recommend or mandate a helmet.

Do consider that in the Netherlands, people cycle 15,000,000,000 kilometers per year (that’s over 800 km per year per citizen, including babies etc.) to put the 50,000 injuries into perspective.
