I was more than a little surprised that Kabul has some pretty serious traffic - but when you're stuck behind a massive ISAF armored convoy, it turns out to not be that surprising in the end. It certain has nothing to do with the transportation gird - as the Afghans don't seem to need traffic lights or signals of any kind, a kind very polite chaos at full speed, horns, and inches between the cars. Our driver assured me that only bus drivers would obey the traffic police.
