Carpooling in Jakarta

Drivers hire "jockeys" to ride with them so they'll qualify for the carpool lane:

Angga, an 11-year-old boy who puts in time as a jockey after school, had just returned from his first ride, beaming. He had earned just under $1 and paid less than 20 cents to return by bus to his starting-point.

A nice application of the Coase Theorem. And a little bit like the casual carpooling phenomenon in the Bay Area and DC, except in those cases the riders actually want to get to the same destination as the driver. In Jakarta they just hop a train back to their starting point.
