TOMORROW: TAILGATE WARNING ON THE WINDSHIELD

A PROJECTOR THAT CAN BE MOUNTED INSIDE A CAR, IN FRONT OF THE STEERING WHEEL, FLASHES THE CAR'S SPEED ON THE INSIDE OF THE WINDSHIELD OR ON A REARWARD SLOPING PLASTIC OR GLASS SCREEN JUST INSIDE THE WINDSHIELD. ALSO INCORPORATED INTO THE "HEAD-UP" INSTRUMENTATION SYSTEM IS A SIMPLE ANTITAILGATING DEVICE. IT PROJECTS TWO VERTICAL LINES ON THE WINDSHIELD OR ON THE SLOPING REFLECTOR, JUST ABOVE THE AUTO'S SPEED. THE LINES COME CLOSER TOGETHER WHEN THE CAR RACES AND SEPARATE WHEN IT SLOWS DOWN. TESTS BY THE BRITISH ROAD RESEARCH LABORATORY HAVE INDICATED THAT THE PRESENT-DAY DASHBOARD IS A DISTRACTION. /HRIS/
