Eh? Inward opening doors are common everywhere I've been. US, Britain, Norway, Germany, etc. For apartment buildings, the outer door might be outward opening, but after that everything is inward opening.

Good luck escaping a fire if your outward opening door is blocked by falling debris.

An extreme example for sure, but there are pros and cons.

(Sliding door might not be the answer either: https://www.buzzfeednews.com/article/katienotopoulos/brave-t... )

Inward opening doors are also less safe when a bunch of people have to escape quickly.

Afaik outwards opening doors are more of an Asian thing, in Eastern Europe, it's a bit mixed but in most of Western Europe it's pretty much all inward opening.

Which is why most fire codes don’t allow them on buildings with a bunch of people in them.
