DETROIT (AP) -- GM's OnStar service is planning to go beyond helping motorists in trouble. It wants to help stop car thieves.
Starting with about 20 models for 2009, OnStar will be able to slowly halt a car that is reported stolen. The radio may even speak up and tell the thief to pull over because police are watching, although that part is still under consideration.
OnStar already finds 700 to 800 cars per month using the global positioning system.
With the current version of OnStar, drivers can call operators for emergency help, and OnStar operators will contact a car if its sensors detect a crash. The service has about 5 million subscribers.
