As I said during our last talk, GPS has the following advantages; First, it provides us with a way to get to the target place. We can go anywhere using GPS even if we don't know the roads or have the maps around us. Second, we can get the information about traffic conditions. We can bypass traffic-jams and go fast. Third, it gives the information about the location of speed surveillance cameras. We can drive while evading monitoring by the police. However, GPS has some disadvantages; Underground or at very high places, it gets mis-information about the location. Additionally, most drivers depend on the same directions and that causes traffic-jams. Some drivers misuse the information about the location of speed surveillance cameras and they tend to enjoy driving too fast. In this case, GPS's can be the cause of the traffic accidents.
