Do public comments actually change federal decisions?

Yes, when they are substantive. Agencies are legally required to read and respond to substantive comments before finalizing a rule, and specific personal comments about real places and real uses carry far more weight than identical form letters. Courts have overturned rules when agencies ignored substantive comments.

The National Park Service is proposing to open about 37 miles of multi-use trails at Mammoth Cave National Park to bicycle use, and it'd also allow horseback riding on a specific 5.4-mile road corridor. This rule would affect visitors, equestrians, cyclists, and park managers who oversee recreation planning. It's a proposed rule, so it's still in the public comment phase before any changes take effect.

In the agency’s own words

The National Park Service (NPS) proposes to amend the special regulations for Mammoth Cave National Park to allow bicycle use on approximately 37 miles of multi-use trails throughout the park. The proposed rule also would allow visitors to ride horses on the 5.4-mile Houchin Ferry North/Ollie Road.
