A common problem with all kinds of navigation devices. Charts that do not include hazards to navigation, maps that are not current, people who actively resist having accurate information published about their area, city lots that have multiple addresses, aviation charts that have wrong locations for nav aids and geographic hazards..... I don't think a map or chart exists than can be 100% trusted as a sole navigation aid.
My point is that although people often blame GPS for navigation errors, in fact it isn't the GPS. It is the base mapping data that is the problem. That problem would be there whether GPS, paper, or some other presentation.
