New product shuts car engines off with a radio pulse

“The product, named the RF Safe-stop, works by sending an RF pulse to a car at up to 50 meters (164 feet) away. The pulse ‘confuses’ the car’s electronic systems, which the BBC said made the ‘dashboard warning lights and dial [behave] erratically.’ The engine then stalls, and the car comes to a stop.  Engineer Magazine suggests the RF Safe-stop could be used for stopping vehicles that are suspected of being car bombs. Likewise, the Safe-stop could cut police chases short or be installed in a fixed area to prevent cars from entering. The Association of Chief Police Officers, speaking to the BBC, said that it would be a safer alternative to stopping two-wheeled vehicles than shooting out their tires.”
