CNN Travel on Trusting Your GPS
CNN Travel’s Jeffrey Weiss: Why your trusty GPS sometimes fails you. “GPS navigation systems aren’t perfect. Most of them are pretty good, but blind acceptance of their advice can become a traveler’s nightmare. … The bottom line: GPS is an amazing aid for the many directionally challenged travelers who nevertheless take to the roads. But it has its limits.” Via @gpstracklog (who is quoted in the article).
