+1 there.
Couple of years ago, I got a call to assist two furniture deliverymen who--following their GPS--drove a 28 foot box truck a mile and a half, down a fire road that was built by the CCC in the thirties, and not maintained much since. It was too rough for a Ford Expedition; I patrolled it on a motorcycle. It took 6 hours with a Kenworth wrecker to get them out. I asked them whatever possessed them to go that way. They said that they were just following the GPS for the shortest route...
