With the alleged drop in private cars entering Jakarta due to the odd even policy there are more taxis around which should be a good thing. However recent trips with the larger of the taxi companies here have again proven otherwise with the drivers lacking both good driving skills and the knowledge of basic places or well known places in the city without me or the wife having direct them at every turning.
They don't use waze or map apps preferring instead to rely on knowledge. Perhaps like car hailing apps they could be allowed to use map apps or gprs to offer a better service.
There are more buses now which is useful and the bus lanes I ride next too are empty most of the time. The traffic on the tool seems heavier and getting around the city is a little more congested than normal so using taxis is becoming a little more costly. And definitely not worth the money if you are navigating.
