The town I live in, Peachtree City, Georgia, has an extensive network of bike/golfcart paths that connect every single building. Homes, churches, schools, restaurants, etc. They're all connected. You can live and work here without a car. You can get anywhere in our city without having to drive on the car roads (you'll have to cross a couple here and there).
Our path system is the most extensive in the entire country.
We're the best-kept secret as well.
Check it out.
Our teenagers drive golf carts (and bikes too). In the fifty year history of our city we have only had ONE death on a golf cart and one death on a bike.
