When I was in SF, my European mind was astonished why bus stops are so often (and why there is a cable to pull, but that's a different thing). Considering that the area was less populated than my city. And we also have speedbuses that stop every second or third bus stop.

It was unreal.

In my city bus stops have 1km between them (sometimes it is 700m sometimes 1.3km) so about 3200 feet.

It is about 15min walk between each bus stop, so when I need to wait for bit longer I prefer to walk to the next bus stop, just to have something to do.
