For All You Libertarians Out There, If You Think that Private Enterprise Will Protect You

How do you handle the fact that the auto communications company OnStar is going to track all the cars with operational units, and resell the data:

OnStar has begun notifying customers that it may continue to collect and use information about the vehicle even if the customer terminates his or her subscription.

In a privacy notice that will take effect this December, OnStar said that it would collect data as long as a data connection was active, including such details as the location and speed of the vehicle, as well as such fine-grained details as the odometer readings and tire pressure.

The privacy statement lists it as being effective as of Dec. 2011, although the statement also notes that the changes were made to the Jan. 2011 privacy statement.

In the privacy notification, OnStar said that it will share the information it collects with credit card processors and data management companies, as well as roadside assistance providers, emergency services providers, law enforcement, and wireless and satellite service providers.

The data collection can be halted, but OnStar must deactivate the data connection. "Unless the Data Connection to your Vehicle is deactivated, data about your Vehicle will continue to be collected even if you do not have a Plan," the privacy policy states. "It is important that you convey this to other drivers, occupants, or subsequent owners of your Vehicle. You may deactivate the Data Connection to your Vehicle at any time by contacting an OnStar Advisor."

Do you have OnStar?  Did you know about the change in the privacy policy?  Do you know whether or not a private individual could hack into your system and track you? 

How about a cop without a warrant?  (It's still in litigation)
