mass rapid transport please

Last Saturday, I went to Setrasari Mall Bandung. I use public transport, that is a small minibus car that carried approximately 16 people (7 seats on the right, 5 seats on the left, 1 backward, 2 seats on the front, and 1 driver - amazing how such a small car can carry that many people). Normal ETA 30 minutes. Last Saturday, it took almost 1 hour for me to get there. Unfortunately, the new fly-over bridge didn't help much. Instead it caused more problems, traffic jams problems. As far as I remember, that bridge were built to reduce traffic jams in the city. Ironic. Now, I have time to daydreaming a bit. Why don't we (read: our government) build a mass rapid transport system, instead of building more roadway. By using public transport, a mass rapid one, it will decrease car quantity on the road, reducing time and cost, reducing pollution, saving fuel (which is critical and crucial for this time). Eventually we will have a better city, a healthy one. No traffic jam problems anymore. No parking problems. No more headache on the street.
