What country is the bus free?

Excuse me, but I was wondering if you could clarify something for me. The paragraph mentions that the bus is free, but it doesn't specify which country this is in. Could you please elaborate on the location where this free bus service is available? Is it a specific city, region, or perhaps a unique program in a certain country? I'm quite intrigued by this concept and would love to learn more about the context in which this free bus service operates.
