Finally, someone has had the kindness to step in and solve the age-old problem of finding your car at the airport. Britain's Heathrow
-- a major hub for scores of European airlines and their travelers -- is about to unleash a new wing known as Terminal 5, and as part of the package, its parking lot is getting an upgrade. A new automated system in the garage will snap a photo of your license plate as you head in, direct you to a space using illuminated arrows and an infrared camera tracking system, then issue a ticket which can be read at a kiosk when you get back. When you insert the stub into the reader, a digital display shows you a 3D map of the carpark, and points you to the exact location of your vehicle. According to planners, the project will reduce traffic, cut carbon emissions by 397 tons per year, and will halve the number of relationship-ending arguments that occur while trying to find a car.
