Unlike HS2, the Indonesian high speed train does not attempt to go to the city center. Instead, there is a slow feeder train to get to the terminal on the outskirts of Bandung that takes almost as long as the high speed train itself. So, Asia has not solved this particular problem either. The main problem with HS2 is that it goes underground through rural areas for political reasons.
High speed trains in France, Germany, Italy, ... all usually go to the city centres as well.
