The picture they took is of the MUNI stop where my 48 bus used to stop, and yes, the Google bus would actually block out the MUNI busses. I haven't experienced it anywhere else though. I think this is basically just a highly visible spot for these buses, and they do interrupt MUNI service during morning traffic. Though I'm not sure they interrupt service any more than any other piece of traffic..
