One too many pot holes
Looks like a tie rod broke. Maybe the bolt just came apart?
When that happens in this part of the world and those type of roads,rest assure it's broken,luckily it seems he was going over a curve and most have not been going to fast,incident like this at high speed can result in death.
Wherever you go, there you are.
