The fatality rate for every million hours spent cycling is 0.26, compared to 0.47 per million driving hours (on-road motorcycling comes in at a whopping 8.80 deaths per million motorcycling hours). For every million cyclists in the US, 16.5 die each year, whereas for every million motorists, 19.9 die each year.The author discusses risk quite a bit more and talks about commute homeostasis and the factor of improved health of cyclists, but in the end he concludes that cycling is a relatively safe activity.
In other words, the odds of dying in a bike crash are about the same as the odds of dying in an SUV crash. The false sense of security that comes from an SUV tends to produce far more dangerous driving behaviour.
Part of my mission at Cyclelicious is to note that bicycling is a safe activity. There's a perception among too many that bicycling is a dangerous activity -- it seems counterintuitive that sitting exposed in traffic on a bike is about as safe as riding inside of a metal cocoon. McGreal makes an important point in his article that our riding behavior can have a significant impact on risk. Following the rules of the road and an educated awareness of traffic risks reduces the risk of injury collisions significantly.
If you want to be a safer cyclist, read Ken Kifer's archived information on bicycling safety. I recommend the book The Art of Urban Cycling by Robert Hurst, which is good for all kinds of city cycling, not just downtown urban cores. I also recommend the League of American Bicyclists bicycling education courses for instruction in safety and bike handling skills. Even if you're an experienced cyclist, you can learn quite a bit from taking the LAB classes.
A hat tip to Paul Dorn for pointing to the risks article. He also posted good commentary on motorist advocacy in Seattle.
