Yuck. In a previous career I was sometimes a camera operator for TV crews and occasionally we shot Motorcross in indoor arenas. The whole arena would fill up with exhaust fumes, it was awful. (I like that gasoline smell but after 30 seconds of not being able to escape from it it's not so nice anymore.) If that is a real photo, i.e. the result of something someone actually did, then I am thoroughly horrified.
I think the truth is a lot of kids used to die in playground accidents. Maybe there's something to be said for trading off safetyism for grit & independence, and goodness knows I like to see my kids taking little risks and trying today what they were too scared to try yesterday, but at a certain point I'd rather have a slightly sheltered kid who's alive and well than a toughened up one who's lying on the ground with a broken neck.
