an artwork with strange contents

A bus with LAX on the destination display, driving on the right, but other than the bus stop on the right, set in the England of a century ago?

It is an artwork entitled "Life is Beautiful" used in LA to promote the Banksy film Exit Through the Gift Shop: A Banksy Film. The movie tells the story of Thierry Guetta, a French immigrant in Los Angeles, and his obsession with street art. The film charts Guetta's constant documenting of his every waking moment on film, from a chance encounter with his cousin, the artist Invader, to his introduction to a host of street artists with a focus on Shepard Fairey and Banksy, whose anonymity is preserved by obscuring his face and altering his voice, to Guetta's eventual fame as a street artist himself. The film premiered at the 2010 Sundance Film Festival on 24 January last year.
