Here is an interesting link to consider:

I am interested in risk analysis (I am in network security so I think about this topic a lot), and recently have been reading a great deal on how humans are poorly equipped to assess risk. We greatly exaggerate the unusual or unknown types of risks in our minds, while underestimating the risks with events that are far more likely to happen, for example death by heart failure, cancer, or as a passenger/driver in a car. Given the scale of those risks, I will hedge that as a cyclist who is exercising and eating well, I am doing more to combat or defer the outcome of the first two or three categories than risking my life! And we all should be pressuring auto manufacturers or our local gov for safer cars and transit ways, as car drivers, passengers, pedestrians AND cyclists [if you are never a car driver or passenger, more power to you but most of us mix and match in these categories].
I think the cycling deaths strike so close to home for us because most of us fear the end - we fear we will not have gotten to do or be everything we wanted, we fear how it will happen. I know at times I do. And we relate to the cyclist killed. So we imagine, this could be me! every time there is a new report on the board of a serious cyclist killed, and come to the conclusion cycling is very risky.
A little girl in our area (12 years old) was killed just days ago on her bicycle by a utility company truck. If I were to publish that here as another vehicle versus bicycling accident, would we relate to it the same way? I don't think so. Some here might relate to it more adversely, thinking perhaps of their own kids, while others might not react as much since the image of a child riding her bicycle down a residential street doesn't so much map with our images of ourselves as adult cyclists out on a ride.
The only way, I think, to combat my fear of a life interrupted prematurely by any kind of death is by living it fully if not daily, then over the weeks, months, and years that I have. Cycling is definitely fulfilling, and I'm not going to give that up.
Plus, I still do strongly believe the more cyclists there are, the more drivers will learn to coexist with us.
So, basically +1 to many of the sentiments already here!
