As someone whose main mode of transportation is a bicycle and who spends much time walking on sidewalks, I know just how dangerous our streets and sidewalks can be because of rogue bicyclists.
I've had dozens of near-collisions with bicyclists running red lights, passing me on Valencia Street on the right when I'm hugging parked cars as a slow biker or barreling at me on a crowded sidewalk.
The San Francisco Police Department is conducting a traffic safety survey and their question four, pictured, omits bad biker behavior. The survey asks: "In your opinion, what are the biggest issues impacting pedestrian safety in San Francisco?"
The choices are "Speed/Aggressive Driving", "Drivers Disobeying Traffic Signs/Signals", "Distracted Drivers", "Distracted Pedestrians" or "Road Conditions".
Nothing about aggressive bicyclists or bikers disobeying traffic laws.
That this SFPD survey was designed without addressing the behavior of bicyclists behaving badly means the results won't accurately reflect all the factors that make our urban streets and sidewalk a hazard to many people.
