What? I’ve never seen that. The elevator needs to know which way you want to go.
i just saw this for the first time today in Romania...

#173> Everyone has shared the frustration of waiting for an elevator that never seems to arrive. Really? Maybe I'm lucky I never had to deal a lot with elevators.
I can’t say I have. The only two times I’ve been frustrated with an elevator were when I was inside one and the doors wouldn’t close, and when someone had pressed the emergency stop, so I couldn’t use it.

#174I am amazed how in US closing elevator doors switch to opening if someone touches the door edge. This results in abusive behavior of people intentionally jamming their arms in the path of closing doors, and delaying everyone else inside the stopped elevator.

That's the case with most elevator doors, worldwide...? If you put your hand in a closing elevator door, it's supposed to open again.

#177> Destination Dispatch [...] are in general worse I wonder if this is an artifact of how the author used random destinations. I worked in a building that used Destination Dispatch, and the common travel pattern seemed to be: - Everyone who is not on the ground floor generally want to go to the ground floor. - People who are on the ground floor generally travel in large groups to the same destination. This happens bec…
Is it because the criteria is wait time not travel time? Destination dispatch would avoid some extra stops on the trip. I just visited a new building with destination dispatch, so it seems to be still around. My EE roommate in college had to build an elevator circuit as a final problem. It was on a bread board and had a bunch of call buttons and had a motor and a clear disk with black squares so it could figure out w…

Yeah, it doesn't make any sense to optimize wait time instead of total time from pressing the button to reaching destination.

I like to think I'm reasonably well-traveled, and I've never seen an elevator NOT do that.
However, I think you might be correct about transit systems, where the blocked doors might re-open a small amount before quickly attempting to re-close, to keep the train on schedule and prevent this behavior.

#179> What if the nearest car is full?
I wonder how do elevators find out if the car is full or not.
I once been to an office building where it obviously didn't work properly.
I needed to get down from a pretty high (15+) floor to the bottom during the evening rush.
The elevator got full immediately but still stopped almost on every floor on the way down.
Each time an awkward scene ensued: a huge crowd of people outside elevator just standing and looking at the crowd in the elevator. Everyone has to just wait pointlessly.

The alternative being closing the doors on the person's arm and likely injuring them to avoid a minor incovenience?
