Fair enough. Not familiar with SF bus system but the bus system where I live, which is considered quite good I think, has each bus line 1/2 mile apart from each other. Almost no one lives directly along a route so there's an extra 1/8 mile average walk just to get to the route, not a stop on it. Fine by me but a lot of people don't seem capable of that for whatever reason. Combine that with the bus not actually going to where you're trying to get and I can see why people aren't huge fans.
