Car jockeys are people in Indonesia who have resorted to informal employment to bypass the gridlock that grips Indonesia's largest cities, especially Greater Jakarta. Like Atappers and ojeks, it is one method Indonesians have become accustomed to in their daily commuting struggle.
How it works 
A car jockey solicits by the side of the road a random commuter who does not have enough passengers to legally use a carpool lane. The jockey offers to go along with the commuter for a fixed price. This is a way to bypass carpool restrictions requiring a certain number of passengers. It also offers the poor a way of making money without formal work. As passengers, babies also make money for their parents.
