I have not been biking in Boston for all that long. However, it does not take an experienced eye to realize that there are multiple parties responsible for safety on the road. I have had pedestrians almost run into me when I have had a green light (and right of way) because they decide to try and cross the street before cars come. I've almost been hit by the BU bus which repeatedly does NOT use a blinker to indicate that it is stopping to pick up students. There are some bikers who do not follow the rules of the road and bike recklessly. That being said, I do know a strong contingent of cyclists who do obey the rules of the road, wear helmets, and signal before turning. There are many more motorists who do NOT act in bikers' best interest as opposed to the other way around. I have seen motorists park in the bike lane, obstruct the bike lane in attempt to get into a turning lane, not signal when they are turning, and challenge bikers into smaller spaces and smaller spaces between traffic and parked cars. To claim that cyclists are the only problem is simply ignorant.
