I would say their maps are inaccurate then (the GPS ones that is) I got a Tomtom here- and its still accurate enough to show if I am parked in the driveway or on the road (I get the feeling that many people are thinking that every inch of the earth is magically mapped every second for GPS- mostly it relies on existing maps that may or may not be accurate in the first place) I know mine not only still shows roads that havent existed in the country for the best part of 40 years, and there are several streams (few and far between in country QLD) that are up to 2 or 3 km from where they are in real life according to the GPS system
