New car stopping device shuts down engines through radio pulse

London – A British company has developed a device capable of stopping cars and other vehicles using a blast of electromagnetic waves.

The RF Safe-Stop uses radio frequency pulses to “confuse” a vehicle’s electronic systems, cutting its engine.

E2V is one of several companies trying to bring such a product to market.

It said it believed the primary use would be as a non-lethal weapon for the military to defend sensitive locations from vehicles refusing to stop.

The BBC was given a demonstration of the device at Throckmorton Airfield, in Worcestershire.

Deputy Chief Constable Andy Holt, of the Association of Chief Police Officers (Acpo), who has evaluated the tech, said the machine had “potential, but it’s very early days yet”.
