    Its just like elevators, really. You put your hand in to stop the doors closing, they open again before touching your arm. Next time they close gently on your arm. Third time, the doors snap shut and the elevator ascends without further warning, resulting in traumatic amputation.

      Wait what? Are there actually elevators “programmed” this way‽ (can this behavior even be changed in the controller?)

      Because I have never “tested” this behavior per se (I mean you mostly want your elevator to move anyway so you ideally remove the obstruction the first time it didn’t fully close…)

        I’ve seen cases where it takes some time to the group of people in the elevator to figure out the obstruction. Because it won’t even touch the object, just reopen again and again.

        So no, elevators don’t do that, and I assume the parent comment is sarcastic.

          Thats what I was hoping, but it was presented so deadpan that theres enough countries in the world that this could theoretically be true for some of them

            I was joking, commenting on the absurdity of a safety system that deliberately gets less safe each time it triggers. Can you imagine the crush injuries and lawsuits if that were true? Not to mention all those movie scenes where someone repeatedly stops the elevator so they can confess their love to someone? They would end in tragedy.

            No, elevators are infinitely patient, and will never close the doors on any object large enough to be a crush hazard. Dog leashes, yes sometimes, but not arms and feet.

            It’s a joke about how the safety system on the car works. From another comment in this thread:

            Based on what it didn’t cut through, his finger should have been safe but apparently Tesla designed the thing to keep increasing the pressure if it detects resistance each time until it can close, which is absolutely baffling. I don’t know of any other safety feature that turns down the safety the more it activates. The fact that it reacts to the exact same conditions differently each time should, in itself, be deeply concerning for any safety feature.
