Does anybody know if there is currently an app, or an app in development that can be used to help you find your car in a huge parking lot? I would think it would be pretty easy to make. Just set the gps location of your parked car. Then use a map that could be more zoomed in than google maps. or maybe just have an arrow pointing in the direction of your car. It could also display the altitude to help people in parking garages. Anybody else think this is a good idea? Should be simple enough to be free I'd think.
