There are plenty of examples in my phone - even _phone numbers_ are an example of this sort of nonsense, certainly keyboards are - but another example is my car, an EV, that creeps forward when I'm not touching the gas (lol) pedal the same way an automatic transmission, internal combustion car might.
I wonder how many of these retroformed artifacts are sitting there in plain sight in the various corners of my life my life, invisible to me, hidden by muscle memory and unconsidered history.
