Against the tide of imports, the Ossis could point to just one successful export. Back in the days of communist enslavement, eastern motorists were allowed to turn right against a red light, unlike their liberated cousins on the other side of the minefields. A brilliant idea, thought Wessi planners: after the fall of the Wall, they promptly began adding little green arrows of empowerment to traffic lights.
A decade later, though, the arrows are disappearing - Munich has just removed the last ones in the city. Why? Because they were pointless.
Despite attempts to re-educate them, the supposedly easy-going Bavarians could not shed their conditioning, and would not drive through red. In east Berlin, though, the arrows work like a dream.
