If one has an American license, is that sufficient to be able to legally drive in Bangladesh ? I read this about Australia http://travel.stackexchange.com/a/5806/4584 but found nothing for Bangladesh. And this post http://travel.stackexchange.com/a/451/4584 made me ask my question
Your post is pretty apt. I have driven all around Asia without a license actually. But, the good thing is Bangladesh accepts International Driving Permit. So, that's what you should apply for (to drive there).
