For any Jakarta's Governor, perhaps, the most relevant and politically sensitive issue is the traffic jam. If he/she can get rid of it, he/she will be remembered, and if allowed by law, reelected for the next term.
Now, if the higher authority decides to increase the gasoline price without his/her consent, should he/she curse the the policy or, silently, praise it?
If I were he/she, I would do the latter. Higher gasoline price reduces the use of private cars, hence less traffic jam. And when my people get mad because of the price hike, I would shrug my shoulder, and point out that it wasn't I but those guys who did it.
And I don't get why the current Governor does the other way around?
