I don't live in the Bay Area, or in the US for that matter, but visited multiple times and the reason for this behavior is that people in the Bay Area are usually more relaxed than in other regions I've been to, like New York or other big and crowded cities, like Bucharest where I live. IMO it's also "fucking rude" to "shoulder check or pass aggressively close". I should be able to walk at my own pace and I don't freaking care that you're late somewhere. What can I say, leave earlier, take some other route or get a scooter. Not my problem and whenever I get "shoulder checked" I do get aggressive and I punched somebody once.
