An estimated 3 million people - one million of them with their bicycles - turned up for a celebration on a highway between Dortmund and Bochum, in western Germany. Germany's autobahns, renowned for average speeds well in excess of 80 miles (130 kilometres) an hour, dropped to an average of near zero as tens of thousands of people sat at a 37-mile table for a cultural celebration titled, "Still Life." Cars were strictly forbidden.
