How to drive a bus on the busiest highway of Bangladesh (N1)

We were taking the bus back to Dhaka from Bandarban. I think it was on 10 Sep 2011. I was wondering if there were any changes to how people drive on highways in Bangladesh, after so much was going on about road safety. I got my answer. These drivers are simply crazy. There were enough traffic signs on the road, but I have a suspicion that these bus drivers think those are there for decorative purpose only. Well, if driving license to be given out as long as someone can differentiate the types of cattle on the road, understanding road rules is to ask too much of them anyway. If you are driving in Bangladesh, please keep your cool, drive safe, and keep praying that you don't meet one these on the road ;)
