@cendawanita you could probably infer people's car commute time by how many toots they post relating to stuffs happening while they're in traffic...or not.
They could be PKL, ( if you can't figure the acronym - but you gotta really try first - drop by and ask ), tukang parkir or work on one those glass tower, overlooking the city and spend their day car-gazing on the company's dime...
