I regularly cycle, walk, and drive in Boston. Drivers are definitely more entitled here. I can rewrite each of your anecdotes with drivers in the villain slot.

I regularly cycle, walk, and drive in Boston. Drivers are definitely more entitled here. I can rewrite each of your anecdotes with drivers in the villain slot. especially the swearing at you when they break the rules parts. And pedestrians, as a group, certainly don't know how to follow rules either - jaywalking is rampant, and I have yet to find a dedicated bike lane that they won't happily clog up, even if it means walking directly on top of the "bikes only, no pedestrians" painted on the ground. >To put into perspective - when you're driving and you have a green light, you generally assume cars approaching the red light orthogonally will slow down and respect the stop signal. Now imagine the situation where you cannot assume this and at every intersection you go through, you assume a car will ignore their traffic light. That's what it feels like to be a pedestrian around cyclists in London. To put into perspective - when you're driving and you are in the right hand lane going straight, you generally assume cars in the left lane will not attempt to make a right hand turn onto a cross street through your car. Now imagine the situation where you cannot assume this and at every intersection you go through, you assume a car will run you over (without even signaling) to make a right hand turn. That's what it feels like to be a cyclist around drivers in Boston. Admittedly, I can't put a driver in the place of the stroller anecdote. But I did have a near miss when a parent pushing their child in a jogging stroller came careening around a blind corner without looking and almost crashed into me (I was walking my bike at the time, heard them coming, and got out of the way.)
