I have asked the question " When does a person who uses a car become a driver?" before on this forum and not had an answer.
Indeed. A driving forum I used to post in ages ago used to use the term 'car operator' to define those people who use a car to get from A to B yet have no knowledge of how they work or how to maintain them, or have few driving skills beyond those required to pass the test (or even less due to losing those skills deliberately or otherwise).
Basically to distinguish a person who might use their car/bike/lawnmower/kite/whatever as a means to an end, from those who are enthusiasts.
If you know who sees this as snobbery then I really don't care any more.
