A video has emerged from Saratov, Russia of a man wheeling his bicycle along a busy four-lane road from a moving car.br br In the footage, which was filmed on May 24, the passenger leans right out of the window and holds the bike's handlebars so that it stays upright and wheels along.br br At one point, he almost loses control of the bike but manages to cling on.br br "Passing motorists were all left stunned by what they saw," the filmer wrote.
