Anyone with OnStar is being tracked, or has the capability of being tracked. Also, as I recall, the Feds got turned down when they requested that they be able to "listen in" on conversations in potential gangster or terrorist vehicles equipped with OnStar.
As for the Black Boxes being installed, the article states:
"The data recorders track a number of items, including vehicle speed, whether a driver tried to step on the brakes before a crash, information about engine throttle, air bag readiness before a crash, and whether seat belts were buckled."
The article gives an example, too:
"Lt. Gov. Timothy Murray of Massachusetts found out the hard way last year.
He crashed a car he was driving and told police that he was wearing a seatbelt and was not speeding at the time of the crash.
However the black box installed in his car revealed he was actually speeding at 75 miles per hour in a 65 mile per hour zone, before accelerating to more than 100 miles per hour.
According to Scott Ferson, a spokesman for the lieutenant governor's campaign, Murray believes he either fell asleep or hit black ice.
The lieutenant governor was not issued a ticket at the time of the accident. However, after police examined the vehicle's black box they handed Murray a $555 ticket for speeding in excess of 100 miles per hour."
Then continues: "Consumer and privacy advocates do not disagree there are many potential benefits from the devices, but insist that proper safeguards be put in place to prevent your car from turning into a spy of sorts for insurance companies that may want to raise your rates."
That last part is what I have doubts about. As I said in the OP, it is bound to be abused in one way or another.
