       | I remember a long time ago encountering an elevator (in the US)
       | where the physical buttons were the push on/push off type so you
       | could cancel using another press, and they also popped back out
       | once the desired floor was reached. Anyone else remember that
       | type of control? It's probably from the 40s/50s. I haven't seen
       | one since.

         | No. But even in the 1980's the dorm elevator where I went to
         | college had a way to cancel a floor select. I don't remember
         | what the trick was though, but it was not a simple toggle.

         | I also recall encountering that sort of elevator panel with
         | push on/push off buttons here in Brazil, it was probably in the
         | 80s or 90s (or at most earlier 2000s), but I don't know how old
         | that panel was. I haven't actually used that panel myself,
         | since there was always an elevator operator (ascensorista) on
         | that elevator; and I believe that these elevators have since
         | been upgraded to a modern panel. And yes, I do recall seeing
         | more than once the ascensorista pulling on the buttons to
         | cancel a wrongly set floor.

       | Elevators are ridiculously configurable. I know there are the
       | famous talks on firefighter mode etc., but is there any in-depth
       | presentation, manual explaining the configuration options, or
       | other documentation for all the ways an elevator can be set up?
       | 
       | For example, I suspect all of these cheat codes can be enabled or
       | disabled based on wishes by the building owner, and aside from
       | parameters like how long the door stays open, the dispatching
       | strategies can be configured too. Seeing the options and the
       | thoughts that go into choosing a configuration would be super
       | interesting.

       | I saw this in an elevator in India recently. The third-hand

       | cancel, so all of us computer nerds were trying to double-click
       | it like you would a mouse, when apparently it's click-pause-
       | click.

         | I've seen elevators that ignore short presses of buttons. You
         | press the button, it lights up, you release, the light goes off
         | and the elevator pretends it was never pressed. Any idea why
         | this is being done?

           | quickly.
           | 
           | Or a third option: it's just shoddy implementation that
           | happens to have an annoying effect.

       | So depending on the manufacturer, one of these:
       | 
       | * Double press the button (like double-click)
       | 
       | * Long press the button
       | 
       | * Press the button 5 times really fast.

       | The article says this is in Japan, but would these not work
       | anywhere?
       | 
       | Also, the Honda CR-V ad on this page (on mobile at least) is a
       | new kind of annoying that I hope doesn't catch on, where it
       | "frames" the web page, occluding the text you're trying to read.
       | It sort of reminds me of dot-com era ad tactics, where no amount
       | of annoying your customers is off-limits.

         | You aren't the customer. :) Their customers only care about ROI
         | on their ad spend. This tactic is designed to benefit them, not
         | you. Whether it does benefit them is debatable.

       | Other things about Japanese elevators
       | 
       | 99% the "close door" button works immediately. Vs say USA where
       | 80% are not even connected and where some are connected but the
       | door doesn't respond for 1-2 seconds?
       | 
       | 95% there are no light sensors, only pressure sensors. I'm
       | guessing in the USA those are mandatory that there is a light
       | sensor that if interrupted, causes the doors to open. In Japan
       | those mostly don't exist, there is only a pressure sensor
       | 
       | In Japan it's not uncommon to have someone exit the elevator and
       | just as they exit, press the close button so the door will close
       | immediately behind them. This is a "sorry I interrupted your time
       | by having to stop the elevator" gesture. This wouldn't work in
       | the USA because the light sensors would trigger the doors
       | reopening.

         | Sounds annoying. If I see an elevator stop at a floor then I'd
         | like a chance to actually get on it, instead of having my time
         | wasted by a futile gesture that might save someone a second or
         | two.

       | In Korean elevators the standard is to press the button once to
       | cancel. Like a normal press. I wonder if these button press

         | I've stayed in a hotel in Mexico that had this feature.
         | 
         | FWIW, I didn't recognize the manufacturer, and it's been too
         | long for me to recall it offhand, but I thought it was a really
         | neat feature. Very useful if you accidentally hit the wrong
         | button or if some five-year-old wanted to see all the lights.
