A HSR is for long distance travel, not for short distances.
You don't ride a motorbike or drive a car to go from Block 120 to Block 121 because the Sheng Siong supermarket is located at the block opposite.  You simply walk over.

Indeed, HSR is not suitable for short distance travel. The average recommended station-station is at least 300 km or an hour ride on a standard CR400 Fuxing HSR. Jakarta-Bandung route however, is less than half or 142km. The decision has to do with cost (vs the Japanese HSR) and the  relatively more dense pop of Java .

If this Indo's maiden HSR operate well and popular in the coming years, there is high chance Jakarta may expand the country's HSR network in the far future. Who else can commit to this project by then looking forward ?
