Narcoleptic Bus Driver?

When we first took a bus into Cambodia, I was concerned that our bus driver was narcoleptic. Not only did he keep drifting over to the other side of the road, he also seemed to keep falling asleep on the horn. I later realised that this is just how they drive here, that all the smaller motos and tuk-tuks just get out of way out of the bigger vehicles. Surprisingly, Kersti seemed to take this all in stride--perhaps aided by her anti motion sickness drowsy meds!
