You were technically in the wrong considering that California stops are never actually legal, but it is extremely reckless to ride at 15mph on the sidewalk, especially if you’re barreling through intersections AND “salmoning” aka riding against the flow of traffic. If you’re going to ride a bike on the sidewalk you should act like a pedestrian, for everyone’s safety. If there is a bike lane/acceptable shoulder, you should be riding on that.
