If you’ve ever driven a car before, you probably know what it’s like to use a GPS. At some point in life you have needed to go somewhere, but didn’t know exactly how to get there. So you plug it into the GPS and then follow the route it selected for you.
Only sometimes, there are some crazy directions. For example, when there is road construction that has not been updated in the GPS system, it will have to recalculate and get you back on track.
One of the biggest inconveniences is the short notice that some GPS will give you when exiting or turning.
