I recently had the chance to visit Jakarta after over 10 years away, and they're finally starting to get some things right. The recent emphasis on public transport is particularly promising: the first MRT (subway) line finally opened this year, there's a lot more on the way, they've beefed up the commuter railways, Jakarta airport T3 is head and shoulders above the old ones, etc. Some bloggage on the topic:

Much of the credit goes to recently re-elected president Jokowi, who's the least incompetent leader Indonesia has had in a while (possibly ever/since independence?) and who's also the prime mover behind the new capital idea. That said, I'm not entirely sold on the idea myself, the track record of other SE Asian countries trying this -- Putrajaya in Malaysia and particularly Pyongyang-in-the-tropics aka Naypyidaw in Myanmar -- are not encouraging.
