And that, are not actually quite the obvious pairing you suppose, because it's very a very different case between following traffic and oncoming traffic you may be in conflict of right of way with at a junction. If I assume nobody can see me until I can see they can see me, that means I have to be out of the way of following traffic, down in the gutter. But experience suggests that being well out of the gutter, very much *in* the way, is better for me. Motorists aren't blind: they can see potholes and road paint, cyclists are not a stretch. IMHO the problem comes when they are seen and then dismissed as irrelevant. With following traffic, you're irrelevant if you're out of the way, or at least as far out of the way as a driver thinks he can squeeze by without scratching his paintwork. So I think sitting in a place that demands careful attention from a driver is actually better than assuming you can't be seen, and that is what will help you avoid a lot of crashes. I can't get eye contact with everyone who might be behind me, it's just not realistic.

Ok, but by the same reasoning, a small car/big truck accident on the road is "inherently unsafe" for the small car occupants. In actuallity, however, it does *not necessarily* follow from this that the biggest vehicles are the safest. > I doubt there are statistics to dispute this supposition. > [collision inherently unsafe for the cyclist] No, but the statistics I've cited do implicitly account for bicycle/motor vehicle collisions. The instances of fatal collisions must be infrequent enough that even the cyclists' relative vulnerability compared to the cars' occupants doesn't make the cyclist at large risk overall. What seems *so incredible* to many people is that cycling is actually *less risky* than many actitivies they don't think of as very risky at all... > Whatever can be done to avoid bicycle/motor vehicle accidents > will primarily benefit the cyclist. Yes, but it's the 'whatever', that may be at issue. Some beneficial behaviors may seem counter to common sense and some common sense behaviors may be counter productive to risk reduction. As Peter points out, assuming you're not seen, or worse, 'invisible', may lead to behavior that actually increases risk. And assuming that every driver out there wants to run you off "their road" isn't productive either. Many have suggested that driver education, cyclist education, public awareness, etc., are beneficial to reducing bicycle and motor vehicle collisions. Improved infrastructure, safe passing distance and other laws may be, too. Better enforcement of existing regulations, yes even for cyclists, may help. I've seen many, many cyclists behaving in ways that increase risk for all road users, for instance, riding against traffic, at night, without lights or reflectors... That's really risky behavior. However, me on my bike in the the left turn lane waiting my turn in traffic isn't risky behavior, despite what some may think. It's the appropriate, legal, and smart thing to do. Yes, I will be "in people's way", the same as I am in my car in the same position. I will be as "out of their way" as is possible and prudent as soon as I can be. Often as fast out of the intersection as the car in front of me. Jon |

[....] Ok so it might even be true that nothing in this life necessarily follows anything else. Throw a coke bottle up in the air and I suppose it may *not necessary* follow that it will return to earth, but I'm willing to bet it will. I do know that I don't want to be in a Mini Cooper that collides with a semi truck and trailer. I don't care if it does *not necessarily* follow that the occupants of the semi truck will be safer than the occupants of the Mini Cooper. My common sense tells me the odds of survival overwhelingly favor the semi truck occupants over the Mini Cooper occupants. The link below is to a graphic photo of car plowing into a peloton of cycle racers in Mexico near the Texas border. There's also a video availble if the still shot isn't graphic enough. According to your statistics all these cyclists were statistically less safe driving to the start of the race with their bikes in tow than they were on the road racing their bikes. Then the unthinkable happened. Your statistics are no respector of persons. Statistics to the contrary don't matter when it's your body flying though the air. http://abcnews.go.com/International...tory?id=4984659 Watch Out and Stay safe. All of y'all. |

Me neither, but again, that's not the point I am addressing. The problem with accessing risk in this case, as is common, is one of selective observation and flawed generalization. Imagine you are in a minor car collision, wearing your seat belt. You are not injured, but a gasoline leak has started a fire. You have time to escape if you move quickly, but your seat belt is jammed. You die in the fire. OK, so you carry a knife to cut the seat belt. What if that slight delay makes the difference? Clearly in this case, wearing the seat belt was as undesirable as being in the Mini Cooper crushed by the semi. But it does not necessarily follow that *not* wearing seat belts is the safest behavior. > Throw a coke bottle up in the air and I suppose it may *not necessary* > follow that it will return to earth, but I'm willing to > bet it will. Depends on whether the bottle obtains escape velocity. %^) That you are willing to wager on the likely outcome suggests an understanding of the laws of physics or at least a sound generalization from observation of a fairly simple circumstance with few variables. But when assessing relative risk of various human activities, the laws of physics are only part of the picture. Hmmm, this reminds me of the falling Coke bottle in the movie, _The Gods Must be Crazy_. > graphic photo of car plowing into a peloton [...] > According to your statistics all these cyclists were statistically less > safe driving to the start of the race with their bikes in tow than they > were on the road racing their bikes.

A tragic incident. Do you propose that the cyclists involved failed to properly prepare for and take evasive action? Do you propose that they failed to make eye contact with the driver, -- drunk, asleep at the wheel,-- before proceeding? The inherently unsafe aspect here is the drunk driver. Sadly, that's not a very rare occurrence. This was not about the physics of smaller or larger bodies in motion colliding.

No more than statistics matter if the drunk driver had swerved onto the sidewalk and into a crowd of pedestrians. Or had crossed into oncoming traffic and struck head-on a van full of kids going to church camp. Both have happened here. Doesn't change the point that cycling is not particularly dangerous. Jon |

I'm still somewhat incredulous, despite your citation. But, I am willing to acquiesce that there has been some movement in a positive direction regarding auto emissions in the US during the past couple decades... I wouldn't want to get all political but there are certainly those that feel these gains come at too high of a price and we need to operate more like the Chinese do with fewer governmental regulations and more conscripted labor. I am looking forward to all y'all burning less sulfur in the diesel motor fuel when you deliver my goods. And, even though governmental regulation is driving improvements in the level of this one poisonous gas emitted by the motor vehicles I don't think that you can conclude that a few failed suicide attempts here and there make it safe to run your car in the garage. As a matter of fact the reference you cite indicates that the subject of this story was pulled unconscious from the garage after three hours, most vehicles will operate for considerably longer than that on a full tank. Also your cited report was created in 1981 testing 1980 model chevys - I suspect that the same 1980 models would produce much more CO if tested today. The late 70's were a period of peak environmentalist activity, but with the 80s came Reaganomics and that whole "greed is good" thing. Today the CDC recommends that you <not/> operate a motor vehicle in your garage: http://www.cdc.gov/co/faqs.htm - I believe this page to have been updated since 1981. And I would encourage any and all motorists to test your theory by going into the garage and fire it up. |

They are what they are. My argument, which is backed up by my common sense, is that a cyclist getting run over by a car, train, bus, or semi trailer is involved in an event that is inherently dangerous, and often fatal, to the cyclist. It is far and away more dangerous for the cyclist than for the train engineer, car, or the bus or simi truck drivers. My point is that it is critically important for the cyclist to act accordingly and use their own judgment and wits to avoid this eventuality. Thass all I'm sayin'. |

Yes, fewer people die of carbon monoxide poisoning when attempting to kill themselves by using car exhausts but it's still possible to to be killed by asphyxiation if the confined space is not ventilated. Catalytic converters removed the carbon monoxide but the carbon dioxide levels are unaffected. In a confined unventilated space with an engine running, the oxygen levels will drop, the carbon dioxide levels rise and any hapless mammals including humans sharing that space will eventually suffocate due to the lack of oxygen. It just takes longer to die but gives more opportunities for the suicide wannabees to change their minds and do something about it. It also increases the chances of being discovered by a third party before the attempt succeeds. You are all welcome to try to prove me wrong but I would recommend you try to do it using a hands on approach.... |

Any outcome other than a safe landing is a worst case outcome. There's no room for alternate outcomes. If airplanes always landed safely you could say flying was essentially a perfectly safe activity. But they don't. You might feel safe in a commercial airliner, but decline to fly with an Alaska bush pilot who flies into wilderness areas where there are no airports. You consider the safety ramifications and you take your chances. I'm not telling you not to cycle on the road, I'm only suggesting if you do and you get run over by a bus there's every likelihood it will be your last ride. So do whatever you can to avoid that eventuality. To me this is common sense stuff. You know like maybe not wearing a helmet when you ride - you consider the safety ramifications and you take your chances. |

If you land safely it isn't particularly dangerous. So in your view danger is based not on the likelihood of bad outcome, but rather the occurrence of bad outcome. Thus, if I go sky diving and land safely, then that particular event wasn't "particularly dangerous". > If you don't land safely it can be extremely dangerous.

So based on this, do you consider cycling as more dangerous, less dangerous, or equally as dangerous as sky diving? Jon |

So do whatever you can to avoid that eventuality. No. If you do everything you can to avoid accidents that may have fatal outcomes then you won't get up to much. No shortage of people are killed falling down stairs, so do I choose to live in a bungalow? No. Do I always take an elevator when one is available? No, I prefer to exercise and use the stairs. How about you? Do you always avoid going down stairs, or make a special point of sitting down and moving down a step at a time to avoid the possibility of a fatal fall? I very much doubt it! If you don't take the probability of the accident into account then you're doomed to never doing anything or living with innumerable cases of double standards in your approach to risk taking. > me this is common sense stuff. You know like maybe not wearing a helmet > when you ride - you consider the safety ramifications and you take your > chances. Which just goes to show there's more to it than "common sense", which is often not common and sometimes not too sensible. I gave up wearing the helmet I used to use for "common sense" reasons every time I rode (at least for transportational cycling) because having read lots of literature on the subject I now know there's no real effect on serious head injuries in populations that take them up. That might not be "common sense", but it's true. I can think up scenarios where they'll help, but I can also think up scenarious where they hinder. The simple fact of the matter is that playing the odds for survival they make no appreciable difference. And it remains the case that cycling just isn't that dangerous. My chances of a serious head injury cycling are a little less per unit distance travelled on a bike in the UK compared to being a pedestrian, and that's with the benefit of my special segregated sidewalk when I'm on foot.

By the fatality per hour study previously cited, home living (active) is significantly *less risky* than bicycling. Sleeping at home makes the odds even better. I would suggest you stay home, but somebody said most accidents occur within one half a mile of home. Sounds like a dangerous place. So I suggest you move. Even better, become homeless, but spend all your time in a home-like environment, perhaps in someone else's home, mostly sleeping... > [...] And when I take my bike someplace by auto I now wear my cycling > helmet in the car.

I thank > Jon for making this clear to me. You're welcome. You'll have to decide whether or not to wear your seatbelt, too, since in the event of a minor firey crash it may kill you. Oh, and just so you don't forget: Cycling is not particularly dangerous. Jon |
