This is, of course, the best method to avoid accidents. If it wasn't obvious before, the varied responses & attitudes this thread has received should convince most that trying to figure out what the mindset/capabilities/reactions etc. of another cyclist might be at any given time is pure conjecture. Your best defense is your own precautionary awareness..... which would necessitate, IMO, a mirror. I feel naked & vulnerable without one, as I would in a car sans mirrors.
