I just read a great story about a musician who left his beloved guitar in the trunk of a taxi cab. In this and most cases, passengers don’t remember the number of the cab they used. However, in this case, they were able to quickly figure that out because the cab was tracked using GPS and the story has a happy ending. While there are many obvious benefits that come from tracking vehicles and other assets using GPS, there are many other unanticipated benefits to knowing exactly where things are.
