I had one pleasant trip where the 'conductor' directed a very pretty young lady to sit on my lap.
I've seen a cement mixer on its side, which fortunately didn't appear to have landed on anyone or taken another vehicle out. Also saw a public taxi that had left the road earlier in the day, that was a mess. I was told there was a fatal injury but of course, that may have been just talk.
I did see a double fatality in Vietnam when a moto concho (only in Vietnamese) went under a truck, where the standard of driving is very similar.
Hmm, no helmet, gloves, boots, leathers and the only rule of the road is biggest wins? I'd rather walk...
