For those 150lb squishy humans, you are a 180lb of mostly the same, but moving 20km/h. Moreover, you are almost totally silent and much harder to see than a car. Add that to the fact that non-cyclists may not be able to instinctively predict what you are going to do next. I'm also a commuter cyclist in SF, and find that it's not that hard to be considerate of pedestrians.
