This is indeed quite bad... but it also reminds me of trains in NL, some have mid section doors that have the same layout as on the photo, with a lit up button that you need to press to open the door. Usually I'd see people try to pull the small handle for minutes on end just to give up and instead stand in the pathway.

Or other doors that have a automatic closing function and you need to pull a handle for it to open again. When entering the train, not everyone pulls the handle so it sometimes automatically closes when someone is in between the door. If nobody knows that they need to pull the handle this can take a while before the horde of people entering/exiting resumes moving again. (Especially hard on old ladies that get stuck :( )
