Not aimed at your post Chubba, just replying in general to the thread dig
First problem - the laws and regs can be different from state to state
Second problem - the source of data on maps may be proposed, current, realigned, service roads, closed, resumed, purchased or just plain wrong.
Third problem - the class of the "track" shown, it could be a public carriageway, a public right of way, an easement or other arrangement such as an access road to service tenements etc.
IE many tracks or roads exist over private property that are easements for access to landlocked properties further up.
The easement exist in law, are mapped etc but are for the use of the property owners/tenants/individuals having business on the property/s and not the public
Another example is rights of way that the owner is required to close at least once per year.
Very common across Gov't controlled lands such as military reserves
