Never lose your car with Google Glass

Imagine that you park your car in an underground parking lot near a shopping center where you have never been before. It would be handy if you are navigated back to your car after shopping.

In modern car parks, you can already see if the parking space is occupied or not by the color of the light above it. In other words every parking space is identifiable. Now it is just a matter of sending this info to your Google Glass so that you are navigated immediately to an available parking spot.
