A British company has demonstrated a prototype 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.
