Did you leave your car running in the driveway this morning before work? You might want to reconsider that practice. Criminals in the area are looking for vehicles that are left running and unoccupied in your driveway... and stealing them. More and more reports are being made to local law enforcement about missing cars, and this practice is often part of the problem.
The best way to avoid having your running car targeted by thieves is to remain with your vehicle while it is warming up.
