Common sense on bicycle helmets

Pro-choicers are not trying to convert helmeteers to ditch their helmets. It seems more the case that helmeteers go to no end to convince pro-choicers their choice is wrong (and moronic).
It goes to such extremes that some helmeteers even endorse helmet use by law justifying this with such tactics as using statistics deceptively, such as using the one that started this thread (cited from a site that endorses carefully drawn, all-ages helmet laws)

A little help, Meanwhile - I thought that the helmet design you're referring was intended to dissipate energy with a two-layer design which allows energy to be better absorbed in the helmet, not prevent head rotation. I admittedly only looked at the information in passing. I'd appreciate a little more info. Thanks!
ALL modern cycling helmets are a two layer design - there is a shell and a liner. The liner is supposed to compress absorbing energy, but it won't do so if the liner fails. Which happens at very low speeds. More, conventional helmets reduce linear impact (at low speeds anyway) but do nothing - or make worse - rotation. Which is the main cause of serious brain damage.
The anti-rotation helmets are something new. See https://www.cyclehelmets.org/1139.html and https://www.bikeradar.com/news/articl...l-helmet-24730
Basically: your scalp slides over the skull in impact, preventing the skull from rotating and jello-ing the contents. But when you wear a conventional helmet you no longer have this protection - the helmet has to be firmly fastened to your bonce to work - and so your brain gets sloshed around. The anti rotation helmets fix this by having a sliding membrane over their outer shell.

Everyone seems to agree that helmets have some amount of effectiveness in reducing injury in some crashes.
It's hard to have a discussion with all the straw men that keep popping up.

But the important question is much larger than that and involves risk/cost/benefit analysis. As an example, few would disagree that IF the perfect helmet existed, a light weight helmet that contributed absolutely nothing to increasing risk of injury [a huge and theoretically impossible condition], people would be at less risk if they wore those helmets 100% of the time including when sleeping, walking, eating and especially while showering.
Like Meanwhile and Closetbikerl, I started out pro helmet since I was and am convinced of the efficacy of wearing a full face, Snell compliant helmet when riding a motorcycle.
But wearing one while cycling is like wearing one while showering, golfing, driving or crossing the street. Even if they did not increase any risks, I would feel foolish wearing one all the time. Knock yourself out. Wear a helmet. No one is saying not to. But you are kidding yourself if you only wear one while cycling and do not wear a full face Snell compliant helmet.
On a macro as opposed to an individual level, one only need look at the stats that demonstrate the loss of health benefits to the public from not riding due to mandatory helmet laws outweighs the speculative benefits from wearing one.

And I always wear a seatbelt and use floss. Seatbelts and floss work; cycle helmets don't. So far building a helmet that has enough padding to be useful in a real accident and is light enough not to mess up balance and cause heat exhaustion has proved beyond our technology. Or maybe the manufacturers just haven't bothered - selling beer cooler foam hats at $200 a time is a hell of a business model.

1. save children
2. save on hospital care / insurance costs
3. allow car drivers to smash into cyclists
Luckily I no longer live in a MHL province (of Canada) but I just returned from a week and a half in Nova Scotia (where I rode happily without a helmet and luckily encountered no busybodies). But I resent the fact that some cop can slap me with several hundred dollars of fine and an optional confiscation of my bicycle if he fears that I won't make the payment.
These laws need to be repealed unless the Helmet Nazis can actually produce convincing evidence to justify such swingeing intervention into our personal lives. They're not going to be repealed as long as lies are being spread about the effectivenes of helmets.

Since I didn't call my opponents' arguments strawmen your response, to attack something I did not say, is a fine example of a strawman argument. For that matter I don't see those with different beliefs on this issue as opponents.

It's an emotional issue. Facts don't matter.

Best successful marketing of an unneeded product since Mr. Coffee sold the public on a silly 'time saving' product that makes bad coffee, but makes it with the illusion it is effortless. The marketing of both products relied on the time tested principle that the consumer will not think.
