London’s Boris Bike hire scheme (or, to give it its full but not-long-for-this-world name, Barclays Cycle Hire) is celebrating its 30 millionth journey. Launched in 2010, the scheme has been credited with lifting property values in the areas it serves; inspiring copycat systems in more and more British cities; and, now, a parody rap in which a would-be thief turns down a German sports car for the street cred associated with the hire bike. It’s not quite Sons of Science (warning, NSFW) but we like it nonetheless.
