Some rental agencies at MSP have employees which are familiar with there being maintained residential roads and many a driveway in Minnesota and Wisconsin that are unpaved yet can be considered to be maintained.

Have any bank card-covered insurance claims or personal car insurance coverage claims for rental car damage that took place on unpaved, maintained roads/driveways/parking lots been denied on the basis of the government-marked/maintained road or maintained driveway/lot being unpaved when it comes to damage that took place under normal conditions for driving on such groomed, but unpaved terrain.

And in winter on all those paved roads, it's not even always possible for the unaided eye to tell what is a paved road and what isn't.
