App to beat Jakarta's gridlock sets download record

Jakarta's traffic jams are a constant vexation for the city's 10 million residents. With the chaos not looking to abate anytime soon, entrepreneurial types have made it their business to help fellow commuters circumvent the world's worst gridlock.

Commuters spend three to four hours a day in their cars on Jakarta's roads, a situation which Indonesian businessman Nadiem Makarim described as a huge waste of productivity. The average speed of traffic is 8.3 km/h, slower than a runner of average fitness covering the same distance in a race.

Yet the Indonesian capital's glaring inefficiencies have also created opportunities for the likes of Makarim, who has launched a smartphone app that lets users summon a motorbike rider to weave them quickly through gridlocked traffic, deliver a meal or even go shopping.
