Then I sure hope no one idly plugs a water hose in
the the fuel filler port of my car!
I guess all those auto manufacturers need to
change the designs to prevent that ignorance, too.
Perhaps the K2 is just too challenging (for some) :-)

Indeed it should work if it plugs in AND if it looks the same, or at least
it shouldn¹t cause any serious harm. In other industries where safety is
at issue that is a firmly enforced rule. Examples, from two industries
with which I have worked: Many lives have been saved since general
aviation airframe manufacturers sized fuel filler ports, or required
retrofit port restrictors, so that turbine fuel physically could not be
loaded into tanks feeding a gasoline engine. Line boys, as they¹re
called, are no more or less cautious than the rest of us, but the theme is
that people make mistakes so the systems in which they work should be
engineered to prevent those mistakes or to prevent them from doing any
harm. Ditto in medicine. Patient safety was significantly advanced when
the oxygen and the anesthetic gas fittings were made different enough that
oxygen couldn¹t come from anything but the oxygen supply (e.g.
noninterchangeable screw threads). Patient safety gurus have also
insisted that wrist bands used in every hospital everywhere not only have
standard language, but also standard colors so that, in a rush, a band
announcing an allergy (red) couldn¹t be confused for a DNR (purple) even
though the words on each are clear. And crash carts should be in exactly
the same place in every hospital ward. Until very recently some surgeons
marked an X on a limb to mean cut this side, while others marked it to
mean don¹t cut this side. You can guess about the injuries which that
lack of a standard system caused. I¹ll wager the same is true in other
industries where the consequences of human error can be significant. I
don¹t know enough about electrical engineering to offer any specific
suggestions; but as a starting point, IMHO: if it fits, it should work.
