This data reflects the UK, not a 3rd world country and my comments are restricted to this dataset.

Included in that same dataset are assaults and sports related injuries, which are additional risky activities.

You might argue assaults aren’t voluntary. My personal experience suggests most assaults are the result of voluntary activity rather than involuntary activity, YMMV.

I’m not being naive. I have lived in a 3rd world country where it wasn’t uncommon to see a family of 5 on a motorcycle.

I would note that you will tend to see, proportionately speaking, more women on motorcycles in those countries for the reasons you suggested.
