A British company has created a prototype that is able to stop cars when electromagnetic waves come into contact with it. The prototype known as an RF Safe-Stop is able to use its radio frequency to puzzle the electronic system in the vehicle. This then causes the engine to cut bringing it to a stop.

There are a number of companies trying to get the product on the market, believing it would be worthwhile to have. Its main purpose would be to work alongside the military as a non-lethal weapon.  It would work as a barrier between sensitive areas that the military use and vehicles that refuse to stop when asked to do so.  Also interested in the device are the police who think it will prove useful to them.

The devise has been tested and a demonstration was carried out at Throckmorton Airfield, Worcestershire. A variety of second hand scrap cars and motorbikes were gathered at the scene allowing it to be tested on a variety of automobiles.

Once the vehicles got too close to the Safe-Stop it sent out radio frequency signals that caused the engine to stall.  The frequency bands used are L and S and are capable of travelling up to 50m at a time.

There have been a number of concerns that some have voiced over the prototype. The first is that it may not be able to bring the vehicle to a stop quickly enough, and the second is that it may have lasting damages on the cars electronic brakes and steering systems.  E2V however, a company trying to promote the device said that the risks would be lower than alternative systems.

Some have said that the prototype would provide a safer way of stopping vehicles, in particular motorbikes. Deflating tyres can be dangerous to those in cars and extremely dangerous to those on two wheeler vehicles.

The overall thoughts on the device is that it is safer to use despite the fact that it will not be able to be used on all vehicles. There are suggestions however that it could even stop boats.
