I am reluctant to accept the statistics from Grist above.

How many of the so-called "bike accidents" are actually caused by cars?  Also, how many happen when people are mountain or sport biking?

It seems to me that the "per billion kilometers" numbers are just WAGs even though some people may believe them to be actually descriptive of reality.

Also, I think there are a number of other questions to ask, as I've already noted.

Safe biking is possible -- I do it all the time.  Of course, I drive a pedalable "Hummer." (OrganicEngines SUV)

Safe driving is never, ever possible.

Every time we turn the key to start a fossil fuel burner, we are killing people and other creatures and poisoning the planet.

If that is not the antithesis of safety, than what is?

Also: every time one starts a fossil fuel burning engine, it is the moral and aesthetic equivalent of french kissing Dick Cheney....and then GW....and then Kenny Lay....and then... well, you get the picture!

The numbers apparently come from "Pucher and Dijkstra. 2003. Promoting safe walking and cycling to improve public health: lessons from the Netherlands and Germany. American Journal of Public Health. 93(9): 1509-1516."

I'd be interested in other estimates, but it sounds a little different when we say they are from the "American Journal of Public Health" than just "Grist." ;-)
