Hi again, and thanks again for trying to make sure the map around your area is correct :)

Can you please confirm what kind of way this is? Is it possible to drive a vehicle up it (with permission)? If so, it should remain mapped as highway=service. highway=path is only for footpaths (i.e. not physically possible to drive a vehicle up them). From the aerial imagery it looks like this is a driveway, not a footpath.

The access tagging (access=private) already looks correct for this way to mark it as private (to all: vehicles, pedestrians, bikes, horses, etc.).

If that’s all the case, it sounds like All Trails may have given you incorrect advice. Would you be able to summarise the conversation you had with them and what advice was given?

What’s mapped in OpenStreetMap needs to reflect what’s on the ground in reality. Changing something which is mapped as a driveway to being mapped as a path might fix routing issues on some clients for now, but if it represents a driveway in reality, someone is going to come along and change it (in good faith) back to being a driveway on the map in future. We need to get to the bottom of the routing issues.

Do you know what map software is routing people incorrectly along this way?

Thanks, and happy new year :)
