This is from
https://www.cyclechat.net/threads/survey-says-roads-feel-too-dangerous-for-cycling.248949/ where I dared suggest that a survey of a group of cyclists where 96% use helmets might not be representative of UK cyclists (last official stat was 36% usage and I think it's fallen):
Given that all children are encouraged to wear helmets have have been for some years now, it would make sense that helmet wearing has increased as those children become adults.
1. But a 266% increase in helmet usage in about a decade? I think that's not credible. Even if all children had swallowed the encouragement and continued, that would still only explain at most a 50ish% increase (based on my recollection of demographics), not a 266% one.
2. And anyway, I think the zealots forcing children to wear helmets in school training lessons and similar has backfired because teenagers ditch them as soon as they're able, possibly because it's made cycling ordinarily - that is, without a childish helmet - into another small sign of adulthood.
Most people I see wear helmets,
I wonder where you're looking. BC clubs?
and regardless of the debate on the semantics of safety, it just feels right that to have some sort of cushioning in between your head and a hard object is going to be helpful
There's loads of things that "just feel right" which are actually more dangerous than doing nothing. Cycling helmets could be another electric socket child safety cover.
(a good example is the chap mown down in central London who sustained a head injury but was wearing a helmet, without which is injury would likely have been much worse)..
I've no idea what example you're referring to, but we'll never know whether it would have been worse or not (no way to test it), helmets aren't designed for colliding with other vehicles and by the time you've been "mown down", you've basically lost already and are appealing to flukes to save you - that's not a good way to evaluate safety measures. We need to look at the effect of helmet usage on casualty rates on the whole and there is basically no effect.
