Bike commuters
I commute to work in Boston via bicycle and have done so less than usual because of harassment from drivers. I find it amazing that most driver's AND cyclists are unaware of traffic laws affecting both parties. Driver's don't realize that cyclists have the same legal rights to ride in a travel lane so long it is not posted otherwise (ie. highways where a minimum speed limit is involved). It's amazing how many times in a single day a cyclist hears "Ride on the sidewalk!" Not to mention a cyclist CAN legally ride on the sidewalk so long as it is not a heavy retail area.
I can say that I stop at red lights, have lights, use turn signals and refrain from using my cell while riding. It is very irksome to see other cyclists not following traffic laws, and even more so when something well over a ton is on the city streets not following the laws either.
