I'm a cyclist, and use my bike to get around town, though I also own a car. Of course I can't completely dismiss your sentiment.

Possibly my most important safety measure is route choice. The streets that I ride on have very little car traffic. This includes separated bike paths, but also quiet neighborhood streets. Fortunately this is possible in the town where I live. In decades of riding, I've never experienced a collision with a car, and my near-misses have been rare.
