There are a lot of place where it is acceptable to take a selfie in public; restaurants, parks, sporting events, and well... generally almost anywhere.

But you know where it might be a bad idea? On a dirt bike track where bikes are in mid-jump as they go past you.
Well, that is exactly what this guy tried to do here and it is safe to say that he failed at it. If you look, it appears the first ride that he tried to high-five attempted to ward the kid off, as he came dangerously close to wrecking there. That didn't matter, as the selfie-aficionado tried it for a second time, only for the second rider to come crashing down on his arm.
