That is what I love about Google is that you can use their tools on them. Had it been the government (especially here in the freedom-hating USA) with cars/cameras, you would have at least gotten added to the Terrorist Watch List just for noting where the cameracars were.
In fact, I bet Google is aware of the fact that people are tracking its cars. I think it would be interesting if, for example, they were to add GPS devices in the cars and have a real-time/frequently updated map showing their locations. (Even better, being able to track a car in your area and seeing the picture feed to make sure your thong/swimming pool does not appear.)
