You parked somewhere near the stadium or bar, but when the concert / party ends you do not have a clue where the car is. The accompanying friends are so clueless. Hopefully you have not lost your Android phone that never forgets anything, and you remember that you have the hot new app, Android, Where's My Car?. With this app, you click a button when you park your vehicle, and the Android uses its location sensor to record the GPS coordinates of the vehicle and address. Later, when you reopen the app, it shows a map of where you are remembered for the site - problem solved!
