Other people's accidents did not always involved a direct collision but many were caused by evasive action because of car drivers (often truck drivers). Maybe we should do a little survey of posters to this discussion group. What was your last on-road bike-related injury? Was it because you were hit by a car? Was it because you were taking evasive action to avoid being hit by a car? Or what was the cause? I suppose if people prefer, they could give counts of all their bike injury incidents instead of just the last one. I don't have much to contribute. Since 1972: I slid out on gravel at about 5 mph creeping down a very steep, short hill on a city street. I scraped my knee. And the front forks of our custom tandem snapped off on a bumpy road at about 10 mph or less. I banged up my shoulder. So that's one crash with the most common cause, which is the road surface; and one crash by a relatively rare cause, component failure. My wife's on road crashes are also two. She was on the back of the tandem when it crashed, but she wasn't injured, just shaken up. And many years ago, on a club ride, someone slammed on their brakes unnecessarily in front of her. She avoided that person as she stopped, but another rider ran into her from behind and knocked her down. Again, no injury, just a fall. We were about 20 miles into an 80 mile ride, which we all finished. More detail on the final crash above: The person who caused the chain reaction crash had slammed on the brakes because they were afraid of a passing truck. But none of the others (including me, leading the ride) braked because of the truck. It just wasn't necessary at all. So that crash was actually caused not by the truck, but by timidity. No, it was caused by reckless cyclist behavior. Every respectable teacher in driver's ed teaches their students to keep an adequate distance from the vehicle up front. One Mississippi, two Mississippi. Simple. Failing to do so will one day result in a crash like you described. It doesn't have to be timidity. It could be as simple as an animal running into the road. You're deflecting again. Tell us about your recent injuries, Joerg. Tell us about their causes. Restrict it to on-road if you like. I'm saying most bike injuries are minor and do not involve cars. You're claiming something else. What's your experience? Depends on what you call "recent". Start with your last bike-related injury and work backward. Stop when you like. Just don't omit any. I do not keep a log book about that. I only keep logs about tire lifetimes, brake pads and such. To find which ones are best. I had a 15+ year cycling hiatus on account of lacking cycle path infrastructure. When that got better I started riding again in 2013. No road injuries since then but several evasive actions required because of motorists. So no injuries in four years or so. Perhaps this isn't such a death-defying activity after all! Maybe you forgot again: 40-50% of my rides are singletrack on an MTB. The road bike miles are largely on segregated bike paths. Those are safe and one usually does not get into accidents there if careful. BTW, I didn't include off-road injuries in my list of two (since 1972). Let me fix that. In 1973 I was taking a shortcut through an industrial parking lot. In the shadows I missed seeing a slot between a scale platform and the surrounding pavement. It swallowed my front wheel, I went over the bars and scraped up both palms. No ER visit necessary. Riding home (about two miles IIRC) was painful, as was doing anything using my hands for a few days. You said on-road though. Ok, I had a "get-home-itis" accident last year. Dirt trail, I was to be Mr.Barbecue that night, it was late, I stepped on it, 20mph, sand patch came ... ah, well, enough speed will get me through that in a jiffy ... a Manzanita branch was hidden in there, flipped up into the front spokes, half a rotation .. TWHOCK .. over the bar. The scrape wounds burned for a few days here and there. Oh well. You now have a complete list of my cycling injuries as an adult, both on road and off road. I crashed my mountain bike many times back when I was challenging myself when riding it, but I was never injured. And again, ever since learning to ride visibly away from the gutter (as the law _does_ allow, despite your stubborn disbelief) I've never had to take serious evasive action due to a motorist. I've hit the brakes a very few times, but never even a panic stop. Gutter bunnies seem to have a completely different experience out there. It doesn't matter whether in the lane or not. At traffic lights or stop signs where only one lane goes straight ahead I usually always take the lane. And that's exactly where my serious accidents happened. So far for your theories. Those kinds of critical situations have significantly dropped in frequency since I use bright daytime lights. I know you don't believe it but it's fact. -- Regards, Joerg http://www.analogconsultants.com/ |

So you're not looking at all injuries. You're looking at only those injuries whom someone chose to take to the ER. It excludes the vast majority of bike injuries precisely because the vast majority of bike injuries are minor. (And Teschke is notorious for carefully selecting data that can be used to promote segregated facilities for cyclists.) The data is similar for other studies. Which? List your last few bike injuries, Joerg. Tell us what they were and how they happened, as I did upthread. Don't omit the minor ones. I do not keep a log of any minor ones. I have listed the serious accidents in this thread. Mine usually involved mistakes or reckless action by car drivers. But that's exactly the point! You claimed that most bike injuries are caused by car-bike crashes. I said that was patently false. By far, most bike injuries are very minor and caused by essentially falling off the bike. (To give more detail: most are due to problems with the surface, like slipping on gravel, hitting a terrible pothole, hitting a slot in the road, etc.) The most common bike injury is listed in hospital data as "minor injury to lower extremity." The bulk of those are, literally, skinned knees. I person might get that from a car-bike crash, but almost all of them come from falling off. Have I heard of a "fall to avoid collision?" Not from the experience of anybody I know. Sorry to say, then you don't seem to know much about bicycling. :-) The cycling organizations that recruited me for various instructor, board member or other officer positions disagreed with you. What you really mean is, your beliefs and my beliefs differ. Now, I know that I've gone through four separate training or certification programs regarding cycling education. I've contributed, through pre-production editing, to two well-respected books on cycling education. I've written many articles for cycling publications, some of which have been reprinted in multiple states and countries. I've corresponded with and talked in person with people who are nationally recognized as cycling experts. As recently as ten days ago, one of them asked permission to use some of my writing (a review of a bike-related academic paper). I bike commuted for many decades until I retired. I've done countless bike trips and tours from overnight to summer-long. I've ridden in something like a dozen countries. I've held multiple offices in my bike club, and for seven or eight years ran our century ride when it won a national award. I've done many century-plus rides, including one double century. Instead of going further with that, let me stop and ask your qualifications. Over 35,000 American motorists die in a typical year. About 750 bicyclists die in a typical year. Every study done on the subject has shown that the health and longevity benefits of bicycling greatly outweigh its tiny risks. Man up, stop whining, and learn to ride your bike correctly. You will obviously never understand what "per mile" means. I know that John Pucher of Rutgers has published (in "Making Walking and Cycling Safer: Lessons from Europe") an estimate from U.S. data that bicyclists suffer 109 fatalities per billion km ridden. Pedestrians suffer 362 fatalities per billion km, three times as bad. Those numbers work out to 5.7 million miles ridden, or 1.7 million miles walked, per fatality. Pucher's later estimates from U.S. data were even more favorable, over ten million miles ridden per fatality. If bicycling is far safer PER MILE than even walking, why do you pretend it's dangerous? -- - Frank Krygowski |

Additionally, the event does not have to actually be death threatening event it only has to be an event that the individual who has the experience believes to be threatening, or hideous, or any other strong fear related emotion. Riding a bicycle under what the rider views as dangerious conditions could, if continued, result in am emotional condition where, regardless of reality, the victim would view bicycles as dangerious devices that required almost super human bravery to ride. In addition this supposed "super human bravery" in participating in a supposed dangerious even might also bolster the individual's self esteem, See guys, how brave I am".

We cyclists can often elect to use segregated bike paths which I always do. Same effect. On most of my paths it would take a car becoming airborne and then flying a long stretch to crash into me. Thing is, they do not have wings. You are afraid of cars. Fine.

Unless, that is, the people who applied to get the lights and vouch for... oops, "study" their effectiveness were simply being a lot more careful than normal riders? Falling off a bike is not the main cause of injury or death. Colliding with motor vehicles is. Car collisions account for about a third of all bicycle related injury accidents nationally -- meaning two-thirds are not car-related. http://www.pedbikeinfo.org/data/factsheet_crash.cfm When was the last time you were hurt on a bike? Were you hit by a car? No but that is because I am primarily using a mountain bike, the way it was meant to be used. The reason I got hurt a lot as a kid was that I used a regular bicycle on motocross tracks without wearing any protective gear. Other people's accidents did not always involved a direct collision but many were caused by evasive action because of car drivers (often truck drivers). In case by "hurt" you meant any sort of injury and not just very serious ones, I had several vehicle collisions with a manageable degree of injury. For example: Driver pulled out into main road, said he grossly underestimated my speed ... *BAM* ... my body dented the side of his Volkswagen Polo (used to be called Fox in the US) so badly that I had to help the old guy getting out. The driver side door would no longer open from the inside. Lots of bruises, a pretzeled bike, and I vowed never to buy such a car. Another: I had a green light, stepped on it, the obviously impatient driver of a Mercedes 280S decided he can still do a left turn before I get there, floored it, didn't work ... *BAM* ... I hit the right rear fender. He fled the scene. Plus a few other incidents. Two of my university buddies were not so lucky. Both hit from behind, in the lane, in the city (Aachen, Germany). Serious with a hospital trip each. One had a ruptured spleen, the other lost a kidney. In one of the cases the offending motorist helped my half conscious friend to a phone booth close by to call an ambulance and then he quietly high-tailed it. You mean that you ran into two cars and it was their fault? Yes. The driver's fault. Amazing! What is amazing about it? One driver made a mistake. It happens. The other driver was reckless and probably in some hurry. There were numerous other such events but I was able to avoid a crash. One of them only because I was on my MTB which has powerful hydraulic disc brakes that work the same regardless of weather. Else I'd have scraped up the side of a nice Porsche. I had one accident with a motor vehicle not caused by the driver. Me in the lane, light turned yellow, driver before me slammed on the brakes. I had sufficient safety distance but at that moment the cable for my front brake snapped. I dinged the rear bumper of the guy's BMW. No damage though because the rear slowed me down enough. I can only assume that either you have a vivid imagination or that you are some sort of idiot that rides much faster then the conditions allow. Huh? I am one of the few cyclists in the area (and probably on this NG) who does not draft or tailgate. If you read again you see that it was simply equipment failure. Happens. It even happened to me in cars, twice. Stepped on the pedal, no brakes. I am reasonably sure that my two wheel experience exceeds your by quite a number of years and I have never, with any two wheel vehicle, hit another vehicle hard enough to cause any visible damage to the other vehicle. Never. No brake failures? Then you were lucky. I also had a few other events such as side wall blow-outs which can make for an interesting few seconds before you get the ride stopped. (I would also add that I have never had a brake cable snap which probably says something about comparative levels of maintenance) It was a fairly new cable. The bike shop owner said it happens, and if it does usually early on. But this is not to say that I have never seen a two wheeler hit a car. A bloke that was in my class in collage hit a car. He was riding a Harley down a sidewalk at what he said was "about 35 mph" and a car "pulled out in front of him". Actually the car was on a side street and stopped at an intersection. He hit the rear door. The results was a dented door and a broken collar bone. I suppose that today this would be described as "an accident" although when it happened the fellow on the motorcycle described it as "a damned fool stunt, that I'd not have done if I hadn't had all that beer". That's stupid behavior. -- Regards, Joerg http://www.analogconsultants.com/ |

The reason I got hurt a lot as a kid was that I used a regular bicycle on motocross tracks without wearing any protective gear. Other people's accidents did not always involved a direct collision but many were caused by evasive action because of car drivers (often truck drivers). Maybe we should do a little survey of posters to this discussion group. What was your last on-road bike-related injury? Was it because you were hit by a car? Was it because you were taking evasive action to avoid being hit by a car? Or what was the cause? I suppose if people prefer, they could give counts of all their bike injury incidents instead of just the last one. I don't have much to contribute. Since 1972: I slid out on gravel at about 5 mph creeping down a very steep, short hill on a city street. I scraped my knee. And the front forks of our custom tandem snapped off on a bumpy road at about 10 mph or less. I banged up my shoulder. So that's one crash with the most common cause, which is the road surface; and one crash by a relatively rare cause, component failure. My wife's on road crashes are also two. She was on the back of the tandem when it crashed, but she wasn't injured, just shaken up. And many years ago, on a club ride, someone slammed on their brakes unnecessarily in front of her. She avoided that person as she stopped, but another rider ran into her from behind and knocked her down. Again, no injury, just a fall. We were about 20 miles into an 80 mile ride, which we all finished. More detail on the final crash above: The person who caused the chain reaction crash had slammed on the brakes because they were afraid of a passing truck. But none of the others (including me, leading the ride) braked because of the truck. It just wasn't necessary at all. So that crash was actually caused not by the truck, but by timidity. No, it was caused by reckless cyclist behavior. Every respectable teacher in driver's ed teaches their students to keep an adequate distance from the vehicle up front. One Mississippi, two Mississippi. Simple. Failing to do so will one day result in a crash like you described. It doesn't have to be timidity. It could be as simple as an animal running into the road. You're deflecting again. Tell us about your recent injuries, Joerg. Tell us about their causes. Restrict it to on-road if you like. I'm saying most bike injuries are minor and do not involve cars. You're claiming something else. What's your experience? Depends on what you call "recent". I had a 15+ year cycling hiatus on account of lacking cycle path infrastructure. When that got better I started riding again in 2013. No road injuries since then but several evasive actions required because of motorists. No f****** way! You were off your bike for 15 years because of lack of "cycle path infrastructure"? Incroyable. I rode to work or school most every day for decades without so much as a whiff of cycle path infrastructure. We had a few nasty accidents and cyclist fatalities in our neighborhood. That was enough. Except for hardcore training riders you rarely saw cyclists. Then they started putting in bike paths and bike lanes and, predictably, that substantially changed things. Also for me. It's that simple. The same way I never walk to the store (well, now I ride) even though in Europe we did that all the time. Hardly anyone else does either. Because it is a 45mph thoroughfare, no sidewalk and often not even a shoulder. -- Regards, Joerg http://www.analogconsultants.com/ |
