And your engagement in disingenuous argumentation is astounding. :(

Show me where I said cyclists die in all motor vehicle collisions? Good luck, because I didn't; I said that motor vehicles were the main source of cycling fatalities (especially at intersections, AIUI), and that helmets are neither designed or tested to withstand the forces of a 2 ton steel hulk of metal hitting a person on a 30 lbs (probably less) bicycle. That isn't a radical statement. Don't engage in strawman in order to paint me as forwarding a point I never did (which I'm not sure why you even would think I would.)

Again: This isn't to say helmets can never help in an accident involving a motor vehicle (if one touches you and you plink over, I could see it helping); only that it isn't designed to help you in cases where you are receiving deadly forces to the head, especially via a car or other vehicle. Again, not that radical. They simply aren't. Helmet companies don't claim they do, and their tests are not designed to check that.

EDIT: meanwhile already addressed what I also thought was a rather obvious point, but I'll reiterate anyway.

:rolleyes:

You still aren't getting it. Many cyclists get into collisions with vehicles. It does not appear that the majority of those collisions are fatal.

If the majority of them were fatal, then it would not make sense to prepare for a "hopeless" situation. But it's not a "hopeless" situation.

You are assuming that collisions with vehicles is always (or nearly always) fatal.

As an example, I happen to know a fair number of cyclists who were in collisions with cars. None of them were fatal. While I have no idea whether a helmet was, in some way, useful in any of these, you can't know that they were useless!

No, the anti-helmet camp regularly brings this issue up as a point that helmets are useless. I'm not arguing (no one can) that helmets are useful in situations that are beyond what they can handle. No safety equipment is useful beyond what it can handle. Of course, this is a tautology ("stuff is useless when it's useless"), and as an "argument", means dumping all safety equipment.

It would seem that, if they are beneficial to children, they are similarly beneficial to adults. And the "solo crashes" qualifier is BS because, while adults may not get into as many of these, they do get into non-fatal collisions with vehicles.

You keep arguing with men of straw.

I'll keep it simple this time, so you don't mess things up again:
  1. The situation that is most likely to leave you dead, as a cyclist, is a crash with a motor vehicle.
  2. In those situations where you are incurring fatal forces from a motor vehicle, you are experiencing forces well beyond what helmets are designed to mitigate.
  3. Therefore, wearing a helmet to mitigate serious debilitating injury or death is pointless. QED.

This isn't to say they are useless altogether; I never said that, I don't think that, and I don't think most of the "anti-helmet" advocates think that. I think the assertion is that they are useless when it comes to absorbing life-threatening forces. If they are saying that they are completely useless, then that is a position I'll not defend. The argument is merely that they serve no more purpose than riding in armor or kneepads and elbowpads.


No, the anti-helmet camp regularly brings this issue up as a point that helmets are useless. I'm not arguing (no one can) that helmets are useful in situations that are beyond what they can handle. No safety equipment is useful beyond what it can handle. Of course, this is a tautology ("stuff is useless when it's useless"), and as an "argument", means dumping all safety equipment.
This is ridiculous on a few points.
  • The camp brings up the issue that they are useless for protecting against serious injury or death, not mitigation of minor injuries.
  • Just as you are applying a blanket to suit yourself, I'll do the same: People are definitely arguing that helmets are useful in situations beyond what they can handle. Just look at all the organ donor comments. People really think you are playing Russian Roulette by riding without one, which is asinine. They are not designed to handle fatal forces.
  • Of course it doesn't mean dumping all safety equipment, pay attention. It means that if people are wearing a helmet as a life-saving measure, which this thread of gems obviously demonstrates is so, they are not helping themselves at all. If you want to wear a helmet because of its ability to mitigate minor injuries, go for it, man. I don't care. As I've already said, I wear one in certain conditions (bad weather) that I think I might have more chance of taking a tumble, knowing it will not save my life but might protect against some nasty and painful minor injuries. If that is the goal, no problem; that is well within their design specifications.



It would seem that, if they are beneficial to children, they are similarly beneficial to adults. And the "solo crashes" qualifier is BS because, while adults may not get into as many of these, they do get into non-fatal collisions with vehicles.
Firstly, no, because something is beneficial to a child does not mean it is to an adult. Children have different things going on, physically. That said, yes, they can be beneficial to adults for (you guessed it) mitigating minor injury (Jesus, I'm sounding like a broken record... not sure why I really have to keep saying this). That isn't a problem. Thinking they will save your life, however, most certainly is.



What is funny about this is that the anti-helmet camp has no problem doing this for their own position!
Blah, blah, I know what you are but what am I.


:rolleyes: The flaw in this argument is assumes that helmets serve no purpose in the many non-fatal vehicular collisions.
I. Didn't. Say. That. Here, I'll spell it out for you: There are some situations, motor vehicle involved or not, where a helmet can help mitigate minor injury. Such as a car knocking you off balance and making you fall over. But if you are incurring fatal forces, it will not help, period. That is what is being said. Helmets do not save lives, especially not on the scale people seem to believe they do. They simply are not designed to withstand those fatal forces. The reason motor vehicles are brought up is to show how silly the argument is: That foam helmets, which are such a necessity that you'd be mad not to wear one, will do anything to help you in the situation you are most likely to die in, that is being hit by a 2 ton piece of steel at fatal speeds. That is simply preposterous.

I believe - and that's all it is, my own speculative reasoning - that the differences in the beneficial effects for children and adults has to do with speed. The thing is twofold, so to say: when a child cyclist falls, it's usually at slow speeds. The forces involved are such that a helmet will often help mitigating harm - it often falls within the limits of helmet efficacy. At higher speeds, the forces are a lot more powerfull, and often way beyond what helmets are made for. Further, and probably most important: the higher the speed, the larger the risk of rotational injuries, not least those to the neck. All of this is, of course, in perfect harmony with the statistics :)

I'm quite sure, really, that helmets will at times save lives. Alas, they may also at times be the factor that kills cyclists.

Sadly, I the original article is gated such that the details of the experiment are fuzzy.

There is however a PLoS ONE paper from what seems to be the same group[1]. The study had 587 active participants. It seems pretty obvious that the research group started out from the point of view that helmets were useful and effective and wanted to investigate how to get people to wear helmets. Not really interesting stuff as regards the question whether helmets are anything other than "courage for the head" (in the words of an early generation of more honest marketeers).

One interesting aside in the paper is their reference to the fact that most participants: 1) believed helmets to be effective in preventing head injury; 2) believed that their own risk of cycling related injury was low. The authors' suggestion is that the psychological manipulation technique called "nudging" should be used in order to ramp up cyclists fear of facial injury in order to increase helmet usage.

Typically, the insitution sponsoring this research into how to promote helmets illustrates their PR with a picture of a lovely with the expensive helmet worn incorrectly:

If you bothered to do any research you'd know this isn't true. When a shell fails, it fails before liner compression. See the articles by the helmet engineer at www.cyclehelmets.org/

Tut-tut -- Closetbiker had a conversation with a helmet tester/researcher who confirmed that a shell may fail after the liner compresses to its limits or at some point between no compression and full compression.

Only a fraction of cyclist-vehicles collisions lead to fatalities.

The fact those fatalites where not helped by helmets says nothing about whether or not the non-fatal collisions were helped (or not) by helmets.

While everyone here continues to argue just how much protection a helmet provides, governments continue to pass laws based on the premise that


bicycle helmets can reduce the risk of death and serious injury by as much as 90 per cent
http://www.winnipegfreepress.com/loc...153191275.html

A local advocacy group presented its stance on the legislation here


http://biketothefuture.org/cycling-n...et-legislation

At the bottom of the page, they say,

The Government of Manitoba must not make the mistake of framing the question of
public health and cycling as being limited to bike helmets. There are other ways
to promote public health and cycling which potentially will have much greater impact

But at the top of the page they say they will not oppose helmet legislation.

Some advocates :rolleyes:

You MUST be trolling. Really. You know darned well that with adults, helmets are of limited or no benefit. I didn't even mention it as it has been brought to yours and others' attention a number of times.

closetbiker 05-25-12 05:14 PM

And after they mandate kids, they're coming after adults because, falling from a bicycle can kill you, and helmets save lives!

Dr. Patrick McDonald, a Winnipeg pediatric neurosurgeon, said the law should cover adults too.

"Where helmets often make the biggest difference is if you literally just fall off your bike and your head hits the road. It's not necessarily a high-velocity injury but I've seen people die from just that kind of a fall."


Crap like this is the reason cycling advocates have to speak up against proganda that exaggerates the risks of cycling and the benefits of helmets.

Paramount1973 05-26-12 12:08 AM


Unlike you, I checked the NYC report your link butchers:

1.It's NOT true that "Nearly all bicyclists who died (97%) were not wearing a helmet": if a helmet isn't recovered, a rider is marked as helmetless; it doesn't mean that he was NOT wearing a helmet! It actually means they don't know. So the stats are actually junk.
I did read the report "...Among the fatalities with documented helmet use, 97% of the bicyclists were not wearing a helmet at the time of the crash. Only 4 bicyclists who died (3%) were wearing a helmet..."

The report also states "...For bicyclist deaths occurring in 2004 and 2005 (n=38), documentation of helmet use was more complete (87% or 33). Analysis of helmet use in this subgroup revealed findings similar to the full group: 97% of bicyclists who died were not wearing a helmet. Of the 38 deaths during this time period 29 (or 76%) had head injuries.


2. Nearly all the dead riders (90%) were male. Females go helmetless at the same rate as males, so if helmets were the deciding factor you wouldn't see this. In fact, possessing breasts had a stronger correlation with not dying than wearing a helmet. If the stats really measured the effectiveness of safety devices rather how several different groups behaved then one would have to include that male cyclists would be better served by wearing falsies while riding than helmets! (To be fair to your source, it does mention the lack of dead women - you just weren't smart enough to see the obvious conclusion.)
The report states "...Almost all of the bicyclists involved in fatal crashes were males (91%, or 199), with males having higher death rates than females in all age groups; 45–54 year old men had the highest death rate. This gender and age distribution of bicyclist fatalities is similar to the profile of bicyclist fatalities in the United States: nationally, men accounted for 89% of bicyclist fatalities..."

This actually tracks well with national statistics, the NYC numbers are not out of line.

Despite the empty derision, hand waving and dissembling, this is easy to understand. Cyclist (typically male) collides with object, typically vehicle. Collides for whatever reason, the important factor here being cyclist-collision-object. Cyclist with helmet on seldom dies. Cyclist not wearing helmet almost always dies and, as a rule, of a head injury. We can deduce from this that a common bicycle helmet is more protective from head injury in a collision than the magical protective properties of the air around one's head, 'scholarly debate' or epidemiology studies on helmet laws. OK, maybe if you tied the study around your head, it would depend on the thickness. I'll use a bicycle helmet.

and it is also obvious that some people are just argumentative.

Anyone who doesn't acknowledge that over 90% of cyclist fatalities are a result of collisions with motor vehicles either isn't being honest, or is ignorant.

The very few deaths to cyclists without involvement of motor vehicles almost always involve some type of high speed impact. The incidence of a fatality occurring from a simple fall is extremely rare and I'd bet my bottom dollar that a cyclist has an equal chance of the same result from a stumble and fall when off the bike.

Public statements like the one from the good doctor I linked earlier, is just plain irresponsible as it implies a degree of danger in cycling that is just not present.

Since cycling is so dangerous that one who does it on a regular basis can expect a longer, and healthier lifespan, promotion of safety equipment is essential!

My only input is that my cousin is a Nurse & has seen icky bike injuries & wont go a foot on a bike without a helmet.
I had a personal experience with my head vs. a low hanging tree branch. It was just a glancing blow, but without my Specialized Max helmet, my gigantic melon would have lost some flesh. Since I have very little hair left on the top of my head & don't enjoy pain I am glad I always wear it riding.

Well good for you that your gigantic melon is now even more gigantic and while I will not deny a nurse would see some people who have been injured on a bike, I'd ask just what the proportion and severity degree of injury is seen involving people on bikes.

As much as many would like us to believe otherwise, those injuries are not any worse or plentiful than people who were injured while not on bikes.

What a nurse is more likely to not see, are people needing care from the many ailments riding a bicycle prevents.

And to that post, I add another instance of a pedestrian who died from a head injury after a fall caused by a collision with a cyclist.

Reasoning for cyclists to wear helmets is essentially the same argument for pedestrians to wear helmets.
