You know Uber, right? Started in San Francisco (where else?), you can now hail Uber drivers in major cities on all continents. They're even in China, even though Didi Kuaidi is giving it a run for its money, offering buses and chauffeur service along with ridesharing. Its Didi Hitch service is expected to pick up quite a few riders over the Chinese New Year holiday.
Uber also operates in Jakarta, but is plagued by the same issue afflicting every car driver: the legendary traffic jams. It is not unusual for riders to request a stop and treat their drivers to a meal so both can resume the trip without the growling stomach.
Gojek is like Uber, but the driver pulls up in front of your door on a motorcycle. They give you the trademark green helmet to wear, which makes you not only their paying customer but also their involuntary mobile billboard, and you climb on the back.
Like Uber, it's a door-to-door service, you reserve and pay online, and you can leave ratings on the drivers. Recently they have introduced the woman-friendly option of asking for a female driver, which is important in this Muslim country. And for foodies (or the plain lazy), you can order a Gojek ride for your lunch or dinner: the driver picks up your order at the restaurant, pays for it, and you pay for both the food and its ride. They also have more conventional courier service.
