In Thailand there was a rule, biggest thing on the road had right of way. That would have been a large double deck bus that stopped only for passengers. They would yield for armored vehicles though. If you were involved in a accident in something like a cab or baht bus, run! Get as far away as fast as you can and stay out of site and hopefully make it back to base unseen. The passenger will be held responsible since the vehicle would not have been there if it wasn't hired. If there was a fatality the passenger would be responsiible for taking care of the driver's family forever. Injuries were negochible, depending on severity.
