Yeah and you can flail your head around looking for the arrow or you can just ask. Especially on a busy elevator lobby there might be multiple cars opening at the same time so you cant even tell from the ding/ding-ding
or just point your eyes a few degrees away to look at the dedicated arrows next to each elevator, built for this exact use case, which indicate whether that specific elevator is going up or down?
I have to assume this is a cultural difference and you just don't have those indicators where you live, rather than "slightly moving my eyes is too hard, better make my problem into somebody else's problem"
