I built a bus for my fictional Farthill City because every major city needs public transportation or else global warming.

Most buses are equipped with monitors for Transit TV broadcasts and to display real-time bus maps to show the location through GPS navigation; the latter is the first of its kind in the United States. The screens have been shut off as of early 2015.[2] Also, as part of Metro's ATMS project, most buses include a marquee displaying the date and time, Automatic Voice Annunciation (AVA) for audio and visual announcements of each stop, and an audio and visual "Stop Requested" announcement. A supplemental audio announcement of "For your safety, please watch your step when exiting the bus" was added to all buses on February 28, 2013 and changed voice on March 2015.

Even though most of the Nabi 40Cs don't have that back thing, like for example in Los Angeles County, OCTA of Orange County has it.
