In New York you can literally watch the rats eating the garbage through the bags. Bins and dumpsters are indeed not perfect but anecdotally after living in both NYC and SF I can say the issue is far worse in NYC and I've seen lots of rats eating garbage in NYC because the garbage is literally piled up on the sidewalk for half a day or more, 3 times a week. In SF I see plenty of rats, but there aren't piles of garbage sitting out, so it's just far less of an issue. This is admittedly my own experience amd observation, I'm no rat expert.
