We're sill waiting for our personal jetpacks, which like all utopian inventions, should have arrived by the year 2000. So excuse us for not getting too excited by technology that "could" ease traffic congestion on terra firma. Regardless, those engineering wunderkinds in Germany are developing intelligent traffic systems to prevent grid lock and enhance safety. Siemens is working on a driver assistance system based on communication between vehicles and surrounding infrastructure — lights turn green as you approach or you receive a warning when a car's speed suggests it will run a red light. Ok, that actually sounds pretty sweet, but we still can't turn right-on-red in New York!
