I have always taken the approach that in order to be safe while riding a bicycle, that you must anticipate that every driver, pedestrian, skate board rider, mother with a stroller, jogger and yes other cyclist too... that they are not paying attention to you, don't know that you are there (or care) and will unexpectedly take the most outrageous and reckless action and then act accordingly.
Does it really matter that you are right, if you end up dead or in the hospital???
