No. 0012 - Car Locator Display

Today, this man saw me aimlessly walking around the parking lot with my arm raised up high with my car keys in my hand; immediately he commented "lost your car huh?" I'm not sure about you but this happens to me a lot. It doesn't matter how sweet of a parking spot I get in the morning, everyday after work, I always manage to find myself walking the "tour de parking lot". How hard is it to put a little tracker on your car and then put a display on your car remote key thing? All the display needs is an arrow, pointing the way to your car. Maybe the arrow can even be color coded to let you know how close you are. I've seen it in movies; car tracker that can track cars across towns. If that is possible, then why not in a parking lot. This seem to be an all too simple solution to a way too common problem.
