I know this won't make you feel better, but you're not alone. It's a sign of urban overcrowding/aggression and it's everywhere in the world and, IMHO, getting worse. The last time I was in London I absolutely hated walking around. Cars bound down alley ways there and speed out into sidewalks without regard for pedestrians. I don't feel quite so leery about walking around in Paris, but then the police presence there is more visible. (It doesn't mean there aren't traffic issues in Paris, there are like in every other city in the world. It's just that I don't feel nearly as threatened by motor vehicles while walking there.)
