Secret new markings...
Secret new markings on police cars will help bring high-speed chases to happy endings. The designs are made of special materials so that they show up brightly at night and in bad weather, but only when viewed through heat-sensitive cameras. They are being tested on the roofs of squad cars to make them more visible to helicopter crews. The markings are derived from stealth aircraft technology, and are being trialled in Cambs and Hants.
