Use an entertainment format to examine what cities in the USA, or worldwide, are kindest, or worst, for pedestrians. Local interest and lots of opportunities for showing mayhem will ensure a large audience.   And a large audience will ensure advertisers. I’m not sure if this would work best as an award show or as a reality TV show, maybe some combination of the two. It would be relatively inexpensive to film a pilot or two and test. There is also an opportunity for travelogue type inserts like they have in the coverage of the Tour de France.
