The Pinellas County, Florida transit agency has done this video to help counter the impressions people get from seeing empty buses around the area. Seeing empty buses often causes people to complain that the buses are too big, are obviously not needed, should be replaced with smaller ones, etc.
Some viewers may be irritated by the "big number" rhetoric: We hear the systemwide annual ridership over and over without any context for understanding it. It's certainly not true that the system's 14m annual rides mean that buses aren't empty a lot of the time, as the video has already explained and justified.
But it's a very worthwhile effort, and transit agencies need do to these things. APTA or some other pro-transit entity could be commissioning them for all transit agencies to use, but home-grown ones will always have some advantage because so many people respond only to data from their own community.
