Inside the Cadillac STS sedan, augmented with a wireless communication system. The dashboard includes a digital display that shows icons whenever a car is within a quarter of a mile. The icon may change from green to yellow if the car comes within cautionary distance.

If turned on, an automatic breaking feature will stop the car immediately in such an event.
