Any trouble closing the back doors?

Do any of you notice people having trouble closing the back doors? I carry passengers on the back seats pretty often and each time it takes people 2 or 3 tries to properly close the doors. I personally do not see any trouble closing them. Everything about them is lubricated too(hinges, locks, door seals, even the damn handles).

So has anyone noticed people be incompetent to close those doors, or am I the lucky one to have butter finger passengers?
