In a country where people flash their headlights to force their dominance over other people on the road, its pretty obvious they are offense drivers, not defensive drivers. Until this "me first" attitude is changed, and people actively care about other drivers or pedestrians, nothing is going to get better. Just travel into Bangkok on the Sirat Expressway on any given morning, there are 100's of drivers flying down the emergency lanes to pass other traffic, not only that, they enter busy ON-RAMPS to pass on the left.....these people are suicidal! Cops? They sit there and watch, or take part in the psychotic behavior, I shake my head in disgust at this horrible culture.
