Given that the study is based on analysis of people who ended up having burns treated in the hospital after contact with hot pavement; it seems quite possible that this(or at least the speed at which it can reach reasonably serious injury) is news to some people.
If the thrust of the paper were “Hot surfaces; a novel mechanism in the etiology of surface burns” that would be pretty dubious. It’s actually more of a public health thing, in the “Burning themselves on pavement, a thing people do; and some statistical characterizations of the circumstances and patients affected” vein, which isn’t going to set the world on fire; but isn’t something one can dismiss as common sense.
