The fidgety man in a business suit repeatedly jabs the call button. And when he pushes both the up and down buttons, you know more about him than you care to know.
However, I contemplate not the circumstances of his childhood and life, but a much simpler question. Why don't elevator designers punish the behaviour by resetting the call status?
It should have several advantages:
- Pressing the button a second time could delay the arrival of the car by canceling the previous call. (It would also require pressing the button a third time, but some users apparently derive pleasure from such effort, so we won't bring it up.)
- You could cancel a call for the wrong direction, if it was a genuine mistake or if you changed your mind.
- It would save wear and tear on the elevator buttons.
Why don't we design elevators like this? Have I missed something obvious?
