I couldn't quite capture it, but if you look closely, the girl on the back of the bike is holding a cigarette firmly between her fingers. We were riding in a cab parallel to this pair, and at stop lights, she would take a puff or two. Argentines loooove their cigarettes and I guess they take them everywhere. Also notice how close the driver is to -- or rather, how he is touching -- the bus in front of him. Perfect example of Argentine driving.
