Watch the Spike Nets Ford Stopping Speeders video to see how a 15 tone truck can be stopped from 30 mph with the help of a... net.
QinetiQ, a global defence and security company, invented the X-Net - a super-strong net with spikes positioned along its leading edge that is able to bring a speeding car to a complete stop in around 75 meters.
QinetiQ's X-Net device is considered to be safer than the conventional spike strips used by the police.
