What skydancer said. It does show they understand the issues.
The main question I'd have is how they have arranged this with their insurance; the article doesn't say anything about it. In my experience, it's generally insurance companies that force helmet-wearing.
Also, this will look very familiar to @bright:
Bungee cords were the biggest cause of injuries, but have since been phased out.
