The prevalent attitude seems to be that traffic rules are more like guidelines and can be broken if it seems "okay" to do so. Driving on the wrong side of the road is for example quite common, and most people do it to avoid making a long U-turn. Someone who I knew was driving a car and had a head on collision with a scooter travelling the wrong way on a highway, and the scooter had three passengers on board it (it's called "tripling" and is also pretty common). Sometimes you get to see cars reversing on highways with fast moving traffic, because they missed a turn and wanted to go back.

Things could probably get better in the future though. In New Delhi, for example - according to a new law, if you are caught in a traffic violation (such as ignoring a traffic signal), you lose your license along with the right to drive for three months. I saw somebody's status on Facebook that this happened to them, so it's not just an empty threat too.
