| cancel a wrongly set floor.

| For example, I suspect all of these cheat codes can be enabled or

| 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.

| 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.

| 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.

| 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
