Pierre Bazin is one of the most atypical agents of the Parisian transport authority. A history buff and an expert on Paris, he shares his passion and knowledge with his passengers at the rhythm of traffic jams or the longest traffic lights.

“He’s really funny,” whispers one of his colleagues. The machinist treats his passengers with anecdotes, according to red lights and stops. He has been a bus driver with RATP since 2006 and is a member of the board of directors.
