I've been pondering the Cambodian driving style since we arrived two months ago. It's certainly slower and less frenetic than in, say, Bangkok. Whilst in England we can say categorically that people drive on the left, in Cambodia it seems that traffic "tends" to the right. However, there is considerable leeway given to this general rule and vehicles career all over the road in a kind of zig-zag dance, trying to avoid the potholes and oncoming traffic. It is not at all unusual to be forced off the road, an incident likely to spark a car chase and extreme violence in some countries - here people don't bat an eyelid. If you happen to be parked on the wrong side of the road, just back out into the street and the oncoming traffic will simply swerve to avoid you, passing on either side without pause. Still unable to get to the other side of the road? No problem, just drive up the street against the traffic for a while until you can force your way over! And as for roundabouts, I am still unable to tell who has priority, those entering or those already going round...but at least they're all travelling in the same direction.
