(UNEDITED) I totally agree with the Aug. 4th letter, ("Bicycles Are Not Pedestrians"). It is annoying when bicyclists ride their bikes on the sidewalks where people walk. Bicyclists should be riding on the roads where traffic is. A bicycle, like a motorcycle, is a vehicle, even if it does not require gasoline. I often have seen bicyclists ride against traffic, which is dangerous!
I think bicyclists should be legally expected as cars, trucks and motorcycles are; be in the streets and not on the sidewalks! I have had bicyclists rush past me while walking down the sidewalk when there was plenty of room in the street. I sometimes think that bicyclists do not care about those pedestrians walking on the sidewalk and think they have the right-of-way regardless. They could at least slow down as they pass those that are walking on the sidewalk as common courtesy if there is no room on the street or if the street is tiny or if there is some other obstruction preventing them from being in the street.
I have also noticed while driving and walking that some bicyclists do not pay attention to traffic as they should be. I have seen them dart out into traffic to cross over to the other side without looking first, but yet, as the letter writer also mentioned, if there is a collision that occurs, the driver of the car/truck gets cited for improper lookout, not the bicyclist, because they are probably viewed as a "pedestrian" and not someone operating a high-speed vehicle that could easily injure someone else. If I am wrong about any of this regarding law enforcement's policies then I will happily stand corrected!
I was taught growing up that bicyclists belong in the street and not to ride on the sidewalk because it is disrespectful to those walking on the sidewalk. I will say, too, that I have also seen many responsible bicyclists riding in the street and following the legal rules of the road, which I think is terrific!
