Five years ago, a young doctor was killed at a zebra crossing in central Bangkok by an off-duty policeman doing 100 kph on a big bike. This provoked public outrage and it looked like action would be taken. It was announced that cctv would be used to monitor the crossings and traffic tickets mailed to offenders. Finally, motorists starting observing the law and stopping for pedestrians at the crossings, which resulted in a huge spike in rear-end collisions.
