A bait car, also called a decoy car, hot car, or trap car, is a vehicle used by law enforcement agencies to capture car thieves or thieves who steal items from cars. [1] The vehicles are modified with audio/video surveillance technology, and can be remotely monitored and controlled. Those set up to catch car thieves may include GPS tracking.

Mousetrap cars are often used in physics or other physical science classes to help students build problem-solving skills, develop spatial awareness, learn to budget time, and ...
Various technologies and sensors that are used include radar (all-weather) and sometimes laser and cameras (employing image recognition) to detect an imminent crash. GPS sensors can detect fixed dangers such as approaching stop signs through a location database. [2] [4] [5] [6] Pedestrian detection can also be a feature of these types of systems.
In vehicle-mounted systems, detection equipment and cameras can be mounted to the vehicle itself, or simply tripod-mounted inside the vehicle and deployed out a window or door. If the camera is fixed to the vehicle, the enforcement vehicle does not necessarily have to be stationary and can be moved either with or against the flow of traffic.
