I have gained a few things from the forums which I've factored into my riding (not sure if it was A and S or another) - example - suggestion that if you point your helmet mounted light at a car you should wag your head while doing so to create a moving light source, which attracts attention so much better than a steady light. I've also benefited from personal conversation with other cyclists: heard a story on a light rail train from a guy who got t-boned by a fellow cyclist on a bike trail and the subsequent, really severe injuries from which he was still recovering. Bike trails seem more safe than they actually are, in my experience.
