An increasing number of auto thieves in the San Diego, Calif., area are finding themselves caught in the act, thanks to wired bait cars parked throughout the city by the San Diego police.
A typical bait car varies by model, but it has an electronic tracking device known as GlobalGuard attached to its undercarriage, which emits a silent signal to the police command center once the car is broken into. The car is then tracked by satellite and located by use of color-coded street maps, allowing police officers to be dispatched right to its location.
