Haha, we’re talking about very different things, my friend! Let me give you a little slice of life here:
In my country, the situation is very different. 100% of cheap motorcycle helmets do not provide any real protection and are just there to help you avoid tickets from the police. Many are just baseball caps designed to look like a helmet at a distance. They are like 5 USD, and are universally bad.
A decent (good visor, OK head protection, no chin guard) helmet might start around 20 USD. Full face helmets would be a special order until fairly recently. You can forget about things like “safety standards”. I would suspect it to be a sticker applied to the helmet without the standard even being followed.
Even now, a full-face helmet with chin guard costs at least a comparable amount to a used motorbike (~135$). The number of people that would spend 150$ on a helmet rounds down to zero, despite road accidents being frequent and severe.
There are many great things about my country, but compliance with safety standards is a… work in progress. One good thing at least is that the speed limit is 50km/hr on all roads, and is mostly followed. This plus traffic leads to fewer high-velocity collisions at least.
