You’ll have to go all the way back to 2013:
But Japanese toilets are a world apart anyway, would merit their own thread.
Reminds me of the wi-fi- & Bluetooth-enabled sex toys that gave birth to the term “screwdriving” (offshoot from “war-driving”) for using your laptop / tablet / phone to find and … influence … other people’s toys in public.
I wonder what cool “<whatever>-driving” moniker we can come up with for taking over someone’s toilet, bidet, or poop tracker. At the moment, creativity fails me.
But I’m sure an idea will ripen then emerge in the next couple of hours. Hope springs eternal.
