Maybe not so much Malaysia but with all the other countries involved, I bet there will be a lot of smuggling, especially drugs and fake merchandise, using these other countries for trans-shipments....
I'm surprised that many passengers survived.
I have seen some very unprofessional bus drivers in Thailand.
The unwritten rule in driving in Thailand seems to be, "The bigger the rig, the more power you have on the road".
Some bus driver drive like they're in a sports car.....
