As someone who lived in Toronto and moved to SF, it's a different scenario. Taxis in Toronto are plentiful, and there are almost always taxis available - just not where you want them so it fits. In SF it's different - there's not enough and they can pick up rides anywhere. That's why calling a taxi doesn't work as well as Toronto (where you can call one and they'll show up). In SF half the time they don't show up because they'll pick up a far on the way.
