Bikers' contempt for traffic laws

The complete disregard for traffic laws by the motorbike riders in the city roads is alarming. Dhaka is witnessing an exponential growth in motorbike traffic which in the short term may not seem to be so much problematic, but the prevailing disrespect for the traffic laws by these bikers in the long run will lead to a complete breakdown of the traffic system. Why do the authorities allow the bikers to ply on the wrong side of the roads, cross the roads when red lights are on, driving on the footpaths and so on? If we do not bring them to book now, the day is not far off when the motorbikes will take the place of jaywalking pedestrians and completely shatter the traffic system. Are we waiting for that to happen?
