You can change Thai Driving Code all you want, they just ignore all road rules and laws, they won't even stop for a Red light or a STOP sign. They drive straight through Zebra crossing with pedestrians inside them, they pass over solid yellow lines, they pass over hash mark areas, they park completely blocking traffic lanes, they park completely blocking Zebra crossings, they park and drive on the sidewalks, they drive in the wrong direction. There is no way any new driving codes would do anything, the only thing that will work is proper training/testing, and enforcement by the useless entity known as the RTP (Royal Thai Mafia).
