Actually, read about Peachtree Georgia.
Peachtree City, GA - Official Website - Paths & Golf Carts
Peachtree City’s hallmark is its 90-mile network of multi-use paths for pedestrians, cyclists, and golf carts. Peachtree City residents can go from neighborhood to shopping centers, schools, and parks through the wooded scenery that makes Peachtree City special.
Oddly, they seem to ignore the idea of multi-modal low speed traffic, even though it was pointed out that the bridge photo above did include a bicycle. Although, perhaps I was just reading about carts... the city page does consider them as multi-use.
