Most everything in Viet Nam is shipped by motorbike across Ho Chi Minh City. Motorbikes get around town much faster than trucks or cars.
This motorbike looks top-heavy with its load, but although it is bulky, it's toilet paper and is a relatively light load. There wasn't much of a breeze the day this photograph was taken, so the driver did not have to contend with shifting balance. He doesn't seem to have much room to operate, however.
