Traffic Hazards in Thailand #2

This family driving along a highway in the south of Thailand was one of the more troublesome of the traffic hazards that we confronted. While Dad was obviously driving at a responsible speed, it was the other vehicles on the road that concerned us. We've driven all over the world and we've come to the conclusion that the Thai drivers are quite possibly the worst. They're not the most aggressive nor fastest by any means (the Middle East wins those prizes), however, they must be the most oblivious. What is it about travelling that compels us to contemplate driving skills, habits and etiquette in a depth that we might not at 'home'? Is it that because we're always moving we more acutely notice the mechanisms of movement and the means of getting around, because quite simply, that's what we're doing, just travelling around. And what else are we to do during all those hours on the road staring out windows?
