In what can only be described as one of the most counter-intuitive auto break-in prevention methods, people in San Francisco are leaving their parked cars with their trunks open in order to discourage potential thieves.
… San Francisco and Oakland have seen a considerable increase in vehicle break-ins in recent months, and things have reportedly gotten so bad that people would rather leave their cars wide open just to show would-be thieves that they have nothing worth stealing. An increasing number of residents have started taking out everything of value from their vehicles, unlocking the doors, and leaving the trunk open as they go about their business. The thinking is that thieves don’t have to break a window to look for anything valuable in the parked car.
