When I tell people that I don't use a GPS device in my car, they are often shocked. The seem to assume that anybody who has a day job in the telecom business should be using the popular devices routinely.
This article demonstrates perfectly what happens when blind faith in technology replaces common sense. A bus driver, staring perhaps a bit too much at the GPS on his dash, sheared off the top of a tour bus by trying to drive through a low tunnel, apparently because the route was displayed on his GPS. Fortunately, the occupants of the bus received only minor injuries. It could have been much worse.
