One thing I haven't mentioned that's quite noteworthy is that just about every major hotel and office block I've seen in the business/embassy district of Jakarta has a security check on the driveway. Armed police, private security guards, both or somewhere in-between will vaguely gesture with a mirror under your car, and check that there's a couple of buldging black hold-alls in the boot before waving you through.
To be fair, I suspect having westerners in the car counts for a lot in their risk assessment. This hotel has a metal detector in the lobby, which is actually a step toward real security, but as in many places, simply packing whatever dodgy goods you have inside a spare laptop casing would do. Some better airports have asked me to boot the laptop, at least as far as the BIOS screen.
