Of course, you formed your opinion without noticing that bike helmets have _not_ helped reduce fatalities per rider. *I believe I've posted graphs comparing bike fatalities and ped fatalities. *Did you spot any difference attributable to helmet use? *I didn't. *Neither has anyone else. The study that covers Australian statistics I cited reports: "Examining the crashes in 2001–04, it was observed that: In 65 of the 113 cases, helmet usage was unknown but 30 of the cyclists were wearing a helmet and 18 were not. About one-third of cyclists wearing a helmet died of head injuries, while about half of those not wearing a helmet died of head injuries." Hmm. So much hypothetical death in your mind, but so little actual death in real life! *Again, YOUR data source says fewer than 9 bike fatalities per year. *That's probably consistent with the national figure I saw for Australia, claiming 16 million miles cycled per fatality. *How long will it take you to ride 16 million miles? A lot more serious injury you don't seem to worry about. Far fewer peds would be squished if they were more observant and careful. So your advice to pedestrians is "be more observant and careful." *But your advice to cyclists is only "wear a helmet." *That's very typical of helmet promoters. It's easy for a ped to be more observant. The only reason I'm still cycling is because I'm extremely observant. If the average peds was as observant as I have to be on the bike, their death toll would no doubt be reduced significantly. Hmm, so cyclists are more likely to be killed than motor vehicle occupants. *Thank you, Frank. By about 12 percent, yes. *And pedestrians are more likely to be killed than bicyclists by *79%. *Why is that not on your radar?

Again, you seem to be visualizing all those as being cases where someone absolutely didn't see the cyclist who was riding perfectly properly, and ran directly into them from the rear - a situation you claim is impossible to defend. I suspect that those incidents include cases where a cyclist swerved into the path of a motor vehicle, since such incidents are separately listed in other studies (and I've linked to articles based on their data). Furthermore, I'd bet a lot that those incidents also include cases where a cyclist rides in the gutter, hoping to appease motorists trying to pass in a 3 meter lane.

And how well did that work for the young racer you mentioned earlier? It worked quite well for several other incidents I also cited. It did not work for the one you gave the most attention to. It also did not work for many, many others. If it had, then bike fatality and serious injury data for Australia would have shown great improvement at the time that helmets became strongly mandated. No such improvement has been shown - especially on a per-cyclist basis. What helmets have done is generate lots of "my helmet saved me!" stories. If Oz had mandated styrofoam clown shoes, I suppose there'd have been lots of people claiming "My fragile clown shoe broke! It saved me from lifetime in a wheelchair!"

Helmet promoters are excellent at pretending cycling is the riskiest mode of transport, and the most important source of serious brain injuries. Never mind the data! Never mind all those killed walkers! Never mind that cyclists are about 1% of society's brain injury problem! Never mind that helmets haven't reduced that percentage at all!

Oh, yeah. You know all the tricks, Frank. Come try that here and see how far it gets you. It works most of the time, but keep your ears tuned and reflexes sharp. Just the other day a bus driver skimmed past with at most about 6" to spare. Imagine you had to dodge something just as it came past. You know, by law they're supposed to give 1m. Try taking control of the lane up Mt Dandenong and see how often the F**kwits overtake on blind corners. And for the record I usually ride about half a meter out, and if there are two or more we ride two abreast to make an even bigger presence on the road. At times that generates more anger, and you have items thrown at you, like spark plugs, beer bottles and MacDonalds soft drink mugs half full - speaking from experience. F**k me, you haven't got a clue. Stop boring me with your common knowledge insults. Not interested in some other part of the world. *I don't cycle there. So Australia runs by different laws of traffic and physics? My goodness you're slow. Different culture toward cyclists. I cannot be bothered discussing further with you, Frank. Your closed mind and obsessive nature is out of control. I won't tell you or anyone to wear a helmet. I might advise it, and particularly in my own backyard where I know the road culture and risks. As long as you stick to your side of the fishpond, you'll be safe enough I guess. JS. |

It's boring!" we'd have chased him out. Usenet and Google Groups has no requirement that you read every post. Skip the ones you aren't interested in. Don't argue in them, then say you won't read facts others raise, because they aren't interesting. Won't read?! Won't read what? (Don't tell me it's in that library where you work, either.) You don't offer anything to read. When you have, I've read it - at least looked at and considered it. No, you just say, "Go and research this yourself, just like I have, or I will simply disregard what you say." I believe that's been said only when you've aggressively asked me for data that's both been previously cited, and is easily found. I'm sorry, Frank, but practically no one else is going to devote their life to it the way you have. That doesn't mean I'm dumb. To get a meaningful understanding of just one of those studies, I would want in depth and *complete* details of everything. There will be missing information. I will have questions. It will take more time, and more digging, and more work... And this would just be any *one* study. Meanwhile, I'm not getting any better at wheelbuilding, or getting that treehouse built, or... If that's what interests you, then go build wheels or treehouses or whatever. All you've been doing here is nagging about imagined slights, giving elaborate excuses for not bothering to learn, and complaining about those of us who have bothered to learn. I'd welcome interesting questions from you, or anyone else. Peter Cole (IIRC) introduced an interesting topic, on details of risk compensation, which illustrates there are new directions that this discussion could go. There's still more to learn. I'd welcome interesting questions, but if you're not really interested, you shouldn't be wasting your time, nor ours. Gee, thanks. |

Again, you seem to think that fear from the rear is imagined, whereas I've shown that in Australia at least it is not. I'm sure that you've proven to yourself that your particular riding area is very dangerous; that at any moment, you might get run down from behind; that there is nothing you can do to prevent it; but that a certified -for-14-mph helmet is very likely to prevent your death. But no, you haven't proven it to me. National data for Australia claims 16 million miles ridden between fatalities, which is better than national data for the US (and US data is not very scary, either). Pure "didn't see him" run-down-from-behind crashes of legally correct cyclists are rare in every other jurisdiction I've read about, so I strongly suspect they're rare in Oz too, especially given the coarseness of your data bins. I know there are techniques to prevent being run down from behind, because I employ them and have taught them. And no matter what you believe, Australian data clearly shows bike helmets are not saving tons of lives. Unless, that is, you consider reducing cycling to be a wonderful way of saving lives. You also seem to think that the cyclist was to blame for all the incidents I mentioned and the statistics from the paper I cited, clearly not true. I don't think cyclists were responsible for all crashes. I suspect they could have prevented many, if not most. But your data classifications lack the detail to prove or disprove this. I suspect that those incidents include cases where a cyclist swerved into the path of a motor vehicle, since such incidents are separately listed in other studies (and I've linked to articles based on their data). *Furthermore, I'd bet a lot that those incidents also include cases where a cyclist rides in the gutter, hoping to appease motorists trying to pass in a 3 meter lane. *It probably also includes many - perhaps, as in the US a majority of such cases - where the struck cyclist was riding at night, and using no lights or reflectors. So all the cyclists were weaving all over the road hoping to be hit by an overtaking motorist? Again: In other places, roughly 2/3 of hit-from-behind cyclists have no rear lights or reflectors when riding in the dark on country roads. Are Oz cyclists better at that? It would be nice to have some information, if available. Yes, I'd advise to wear a helmet. It did not work for the one you gave the most attention to. What are you talking about? *I recalled several incidents from memory and a link to one news article to which you refer. What was that young racer's name? You spotlighted the article on his death. Was he not wearing a helmet when he was run down from behind? It didn't save his life, did it? I cannot fathom your line of reason. * Yes, that's obvious. My line of reason usually involves detailed examination of data. Unfortunately, the data you've provided to bolster your claims doesn't allow that - it apparently groups many different crash typed into one. FWIW, I have two sets of friends who have bicycle toured extensively in Australia. None of those folks mentioned anything unusual about risks, traffic patterns, near misses, etc. I assume that's because things were not much different there. Certainly, I've never encountered any articles on the uniqueness of Australian road riding - the unique need to be ever-alert for murderous motorists, for example. Sounds to me like you're firmly in the gutter bunny camp. *Move out and control the lane when the lane is too narrow to share. *They'll wait and pass only when it's clear. *That's very common knowledge.

Half a meter out _is_ gutter bunny territory. That alone explains your experience with near-sideswipes. Try reading _Cyclecraft_ by John Franklin. There are things you need to learn. and if there are two or more we ride two abreast to make an even bigger presence on the road. *At times that generates more anger, and you have items thrown at you, like spark plugs, beer bottles and MacDonalds soft drink mugs half full - speaking from experience. *F**k me, you haven't got a clue. Stop boring me with your common knowledge insults. OK, never mind. You are, apparently, a hell of a man to continue cycling in a place so dangerous that any other mere mortal would be road kill! I'd probably be smashed flat within half an hour of arriving, because my riding techniques would be useless. That is true even though they worked for me in at least 40 US states, in several Canadian provinces, in England, Scotland, Wales, Ireland, Sweden, Finland, Estonia, Poland, the Czech Republic, Austria, Italy, and Switzerland. You're also very perceptive to realize that ordinary physics does not apply to bike helmets, at least in Australia. And that ordinary data analysis does not apply to Australian road dangers. And that even though, on average, it takes 16 million miles to produce a biking fatality, in your case it almost happens every day - and that your helmet is the main thing saving your life. I do hope some mainstream scientists make the trek to explore the wonders of your area. If the dangers are as great as you say (um, despite data to the contrary) and if a little styrofoam is so much more effective than physics predicts, they should stop working on whatever they're doing and talk to you. Just think - military tanks could be so much lighter, if styrofoam replaces battle armor! And a little styrofoam around the perimeter of a motor vehicle would probably make motorist traffic deaths just an unpleasant memory! (I could point out that motorist traffic deaths are FAR more common than bicycle traffic deaths, but I'm sure you've already worked that into your philosophy.) - Frank Krygowski |

"There were speed bikes, helmets, sunglasses and even a sports watch scattered across a large distance..." So how does this incident fit into a helmet promotion scheme? Nobody has ever said that such tragic events never happen. They are, however, very rare, and one of the smallest parts of the bike safety problem - if you can call it a problem at all. For each cycling fatality, you _could_ do newspaper articles on several pedestrian fatalities, and make them sound just as horrible. This is true in the US (where about six peds die for every cyclist), in Australia and in Canada. It's probably true most everywhere. But nobody would expect that the pedestrians should have worn helmets. - Frank Krygowski |

James considered Tue, 7 Sep 2010 17:58:56 -0700 (PDT) the perfect time to write: Half a metre IS gutter hugging - any closer and you'd be risking a kerb strike with a pedal. What drugs are you on? Have you ever watched the cyclists in the TDF on the final stage ride down the gutter to avoid the cobbles? Man, if you can strike a pedal on the gutter from 500mm out you must have the widest set of cranks and pedals known to man. Do you know how far 500mm is? In Australia the concrete gutter I would guess is at least 200mm wide, and I ride about half a metre from the edge of the concrete - hence half a metre from the gutter. It is not advisable to ride so close that you actually ride on the concrete of the gutter because there is often a lip between the asphalt and the concrete that can make traversal dangerous for the uninitiated. Try two metres - it is about the distance from the kerb that the driver of a motor vehicle sits, and is where you need to be if you want to be sure that they notice you. LOL~! ROTFL~! 2 metres if you want to be sure of not only abuse but at least a confrontation, and probably side swipes before someone runs you off the road and beats the living **** out of you - that's if you don't get knocked off first. Jeez, we spent 2 hours at the Ringwood police station not long ago giving statements because some nutter drove a group of us off the road and got out for a fight. Not that long ago a regular TV celebrity broke a cyclists finger during an altercation about riding too far from the gutter. Just move over (to about 1-1.5 metres) to let them past when it IS safe for them to do so. You're as nutty as Frank. Try that in Melbourne or Sydney for any length of time and see how you go. I hear Brisbane is more friendly when you chicken out. You seem to have difficulty with the difference between riding assertively and riding obnoxiously. You seem to have difficulty understanding the road users culture and attitude toward cyclists where I live. Of course, if you ride like a prat you will be treated like one. There may be a very small minority of drivers who treat all riders like that, but at least you can be sure that they have seen you - and a soft drink isn't nearly as likely to kill you as the motorist who doesn't even know you are there. I don't know when I'll stop laughing at you, Phil. You should still report assault to the police though, and collect the projectile as evidence. Please don't get me started. The police here don't know that cyclists are allowed to ride two abreast, or that cyclists are permitted - if not encouraged- to make a hook turn at any intersection that they want to turn right by http://www.vicroads.vic.gov.au/. I just had the hook turn argument with a police officer at Ringwood station! That's the result of discriminating against cyclists with things like MHLs, or maybe the cause. *You still don't have to accept it. No, it's because cycling is not part of the Australian culture as it is in other parts of the globe. I've ridden in the UK, and I have friends and family who've cycled and raced in Europe. It is true that cyclists on the roads in these places are far more accepted by the motorists. Cadel Evans has said as much to the media. He was abused while out training several times when he returned here at the end of last season. JS. |
