Unlocked double doors create their own hazard. There is the tendency to bust through them saloon style, partly out of hedging your bet for which one is unlocked, only to lay a Loony Tunes like booby trap for anyone following behind you:

In fairness though, most double doors aren't spring loaded like those idiotic saloon doors are so wouldn't hit people in the face in quite such violent fashion.

They are though. Door closers offer some resistance on opening. Closers also close. Most closers are hydraulic and some use springs

That still would have happened with a single spring-loaded door that swings both ways, which are the real problems in play.

the kid was hit by only one door. the other is irrelevant

It is actually a horrible video. Poor boy. But of course it shows the saloon door problem.
