Describe the uses of GPS map
This is far safer because a driver of a vehicle doesn't have to consult maps while driving. It also removes error (for example going the wrong way down a one-way street). Sat nav systems can also give extra information like estimate time of arrival, position of speed cameras etc. GPS can now be used to monitor a vehicle's position if it has broken down (extra safety feature) or has been stolen (termed as vehicle tracking system).
In case of airplanes GPS can also pinpoint its exact location in case of an accident that allows search teams to quickly respond to incident.
