I can see some merit in your thesis, but I shall attempt to challenge it on 2 main grounds:... but I'm still working on my thesis (for which I have utterly no evidence) that helmet normalisation here is a symptom rather than a cause. The root cause is the perception that "cycling is quite/very dangerous". But if you could magic helmets out of existence I still suspect we'd be in the same position that we are now with respect to people being shy of cycling: because it's considered dangerous.
- you're ignoring how seeing other people wear a helmet will give quite a strong impression of danger.
- you're ignoring how the helmet manufacturers devised then promoted their devices.
I think the data (for helmet wearing) will show a pretty strong correlation with the latter event. Numbers don't lie, they say ...
