I saw this thread, and I was about to make a wise guy suggestion like, if you're worried about someone watching you, then put it in someone else's car. Or, better yet, put it in a neighbor's car for a while, so it's still in the right neighborhood and almost the right position at night. After a few days/weeks, put it in another neighbor's car. Etc. But you have a real use for it, if you find out how it works, and your car is ever stolen.
