I saw this in an elevator in India recently. The third-hand instructions we heard were that you double-click the button to 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?

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…

> 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.

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 stay…

“From the Pit to the Penthouse” gives a lot of insight. All from a hacker perspective, but fascinating and fun.

In the USA close door button is generally gated behind the firefighter's emergency operation key being activated from what I understand?

> 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.

> You aren't the customer I guess they are trying hard to keep it that way. I do buy vehicles from time-to-time though, so I think I am a potential customer.

You missed the point. Honda may have some targeting data they send to the ad provider but it’s those ad servicers who come up with this format and their customer is both the site and the company the ad is for. It’s not you as the customer the format is made for, and Honda didn’t make it themselves either.

I don't know why someone implemented it specifically, but I can think of 2 possible reasons: (1) To prevent accidental presses, and (2) prevent maliciously pressing every button quickly.

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

You don't think that before doing this gesture, the individual would check if there were people waiting to get on the elevator?

The elevator of my building does seem to respond to close but it’s not super instant. It’s common for the people left in the elevator to press the close button which theoretically should work.

Could also be a debounce mechanism to cancel out multiple presses too close together which is just a reality on switches even if you physically only pressed it once.
