Then there's the theft protection question. Making the player stay in the car "by default" is asking for trouble.

How did I know you were going to say that? If you saw where I work, you'd laugh about the security issue. I'm so far out in the middle of nowhere I have to use satellite for my internet connection. There are only four employees on location and all of them happen to strongly believe that theft is morally abhorrent. Not to mention that I can see my car from my window. I do have an empeg bag and I carry it with me when I'm in more populated areas.
