If you aren't ready to hop on a motorbike and join the craziness of HCMC traffic on your own - then do the next best thing - hire a cyclo driver to give you a chance to be a part of the transportation culture.
Instead of cyclo-ing around District 1 where most of the tourists hang out - get out of the tourist circle and head to District 5 and ChoLon market to begin your tour.
Ben - my cyclo driver - was so great I have hired him multiple times in HCMC. Just tell him how many people are coming and he'll round up a bunch of his friends with their cyclos and they will peddle you among the traffic and through the local streets and sites of District 5 and District 8 for 2 1/2 to 3 hours!
This is the best way to capture photography and video of the motorbike culture in HCMC - you are riding along at a slow pace and can get up close to the subjects for photos. You'll be absolutely mystified as you drive through the city and get out of the touristy District 1.
