Anonymous, my ass. There is a cellphone and a GPS built into the onstar unit along with the equivalent of a MAC address. And I am sure they can run an SQL statement against their database that will pull up your bill of sale when supplied with that MAC address. Hell, I bet they even have it indexed for performance. I hardly call that anonymous.
I am sure the same group who makes money off those red light and speeding cameras are negotiating for this data. Probably not law enforcement directly, but some other company and they'll just call it civil or some BS like that.
And they won't help you track your stolen vehicle unless you are a subscribed customer, even though they have the known location. Just not something they can crunch en masse. Inidividual issues like this are not money makers.

So they sell the data to retailers so they can buy locations that will be more convenient to you and reduce the amount you drive, or they sell it to the government so they can plan roadways that will benefit the community. Also, if they track your vehicle no matter what, wouldn't that be helpful if it is ever stolen?[/citation]
