GPS tracking devices has truly made going around much easier than ever before. And in the beginning of time there were not even any regular maps to look at. People relied on the stars and basic knowledge and visual knowledge of their surroundings to get around. But now GPS which stands for Global Positioning System has made it much easier to drive around and even walk around. These little devices will tell you where you are any where on the planet and if you put in a destination it will tell you how to get to your destination the quickest way. And if by mistake you take a wrong turn the little device will work out a new route for you so you can find the next quickest way.
My uncle that drives a minivan has a GPS Device in his car and since he has relied on this so much he does not even know how to get around his neighborhood sometimes. It is not a bad thing but this is just to show how global positions systems has changed our lives. Years ago it was only available for the Military and then made available to air liners but now regular people like you and me can get a GPS Device any where and any time and use it any way we want just to make getting around much easier.
