A company is the UK has demonstrated a prototype device that can be used to shut down a running car engine, the device is called the RF Safe-Stop and it can stop cars and other vehicles using electromagnetic waves.
According to the BBC, the RF Safe-Stop uses the electromagnetic waves to ‘confuse’ a cars electronics system, and shut down the vehicles engine.
The device which has the ability to stop a cars engine could be used in a number of applications, and the UK Police have already shown interest in the RF Safe-Stop.
The BBC saw the device being tested in the UK on a number of vehicles, and a car drove towards the device at 15 MPH, and when it got close to the RF Safe-Stop, the cars dashboard warning lights behaved erratically and the engine of the car stop, the car then came to a rolling halt.
The RF Safe stop can apparently be used at a range of up to 50 meters, and could possibly be used by the Police in the future to stop stolen cars.
