CRACKPOT, UK – In England, drivers have almost driven off a 100-foot cliff because of GPS guidance, according to TG Publishing. Drivers going to the village of Crackpot are routed onto a dirt road that ends in a 100-foot drop. While no one has driven off the cliff yet, several have reportedly come close. Users of the Smartnav GPS navigation system are affected by this problem, which apparently uses the dirt road when going to and through the town. Smartnav has temporarily removed the routing from its computers.
