Another innovative idea was to use mimes to improve both traffic and citizens' behavior. Initially 20 professional mimes shadowed pedestrians who didn't follow crossing rules: A pedestrian running across the road would be tracked by a mime who mocked his every move. Mimes also poked fun at reckless drivers. The program was so popular that another 400 people were trained as mimes.

UPDATE: Octavio Isaac Rojas Orduña sez: "Antanas Mockus was Bogota's mayor for the 2001-2003 period. Luis Eduardo Garzón is in his place now. So, this news originally took place during 2003."
