If you want to see what a "physicians view" of bicycle safety looks like look at.

Very standard stuff. Use lights, don't drink alcohol and ride, stay away from cars driven by people who have been drinking alcohol... Wear a helmet and there should be laws requiring helmets.
All in all, mostly useless.
Unfortunately many traffic engineers view bicycles as an annoyance. My fair city asked for comments on a proposed bike path that went from nowhere to nowhere, but it went partly on park property so the park district so maybe they would pony up some of the money to build the useless thing.. Except all comments were ignored. They have money to spend and that is what matters.
