Junk said:Concrete - can you substantiate that?
I'm getting that from an article a read a few years back in a popular mechanic mag. It was mostly talking about things like northstar in the GM products and how they have been used by rental agencies to track rental cars and issue fines to renters when they speed or go outside their "permitted" area. Also in the article it pointed to how the government could acquire this information if they were watching you or something. That's all.
