Off the top of my head, this is what I remember. I could be wrong.

A large fraction, like half, of bike accidents are of the cyclist falling off his bike without colliding with a pedestrian or other vehicle. My conclusion: the cyclist's skill has a big effect on this risk.

Of the car-bike collisions, half of them are the cyclist's fault. Many are predictable situations, such as riding on the sidewalk and passing over a driveway. The most common way for a cyclist to cause a car-bike collision is to ride in the wrong direction. Conclusion: knowledge, skill, and compliance with laws has a huge effect on cycling safety.

If we could normalize bike injury statistics for cyclist skill, I think we would find that skillful cycling is extremely safe, compared with most other modes of transport.

I've been cycling for transportation since 1975, and I'm pretty happy doing it. I've been injured a few times, but not permanently. The worst was a concussion. I now teach skills in cycling in traffic. I feel that now that I know how to share a lane when appropriate and when to take a lane to myself, drivers treat me with respect and help protect my safety, generally speaking. Of course there are exceptionally bad drivers out there, and I think I'm pretty good at anticipating their antics.

Take a skills course. It will pay off.
