I'd claim that cyclists tend behave a lot more like other motorists than like pedestrians The speed difference between a cyclists and a pedestrian is usually bigger than that between a car and a cyclists, at least in urban traffic. Pedestrians can be very unpredictable and they don't tend to signal very clearly what they are about to do, not to mention that a pedestrian can stop or turn around pretty much instantly.…
So, I live in Shanghai, which hopefully qualifies as "urban" with a population of over 20 million people (according to wikipedia, almost 10k per square mile, healthily above LA). All of the following situations are routine: 1. Dedicated bike lanes. 2. Bikes hiding along the side of a street without bike lanes, hoping not to be killed. 3. Bikes using the sidewalk. Sharing the sidewalk is far and away the safest thing…
Bicycles and scooters on the sidewalk, ridden by inconsiderate riders, are common, irritating and dangerous. The same is true of cars driving in cycle lanes or service lanes, and the myriad other thinga car drivers do to make life difficult for cyclists.
Sure, cycling on the pavement may be in your own self-interest, but it is strictly bad for pedestrians. Why should they have to change their walking pattern for you? I will give way to electric scooters on the sidewalk, not because I don't mind them, but because it's less unpleasant than a collision or being shouted/hooted at.
