just be glad you're not riding with these distracted idiots or perhaps tremble in fear that they're on the road in the first place. sure, nav systems are wonderful, but you've still got to keep your eyes on the road as these drivers forgot. i'm pretty certain these shining examples are future darwin award winners.
Navigation System On, Brain Off: Brad Adams, 52, crashed his charter bus (carrying two dozen high school softball players, who had to be sent to a hospital) into a pedestrian bridge in Seattle's Washington Park Arboretum in April (bus: 11 feet, 8 inches high; bridge, 9 feet, 0 inches). Adams said he missed warning signs because he was busy following the navigation system. [Seattle Times, 4-17-08]
Five days after that, in King's Lynn, England, a Streamline taxi minibus had to be pulled from the River Nar after the driver, who said he was obediently following the navigation system instructions, drove straight into the water. [Lynn News, 4-23-08]
