This is simply a suggestion for the development team.
A few weeks ago, my family and I had gone to a large theme park and as you know, the parking lot is massive. As we were getting out of the car, I thought it would be awesome if I could create a personal navigation point at the location of my vehicle so that when the day was over, I would easily be able to find my car. This could work at places like airports as well. You could send your custom point to a friend who is going to pick up your vehicle, someone who has no clue where it is.
Again, just a suggestion to add a small, but useful feature to this wonderful app.
