I haven't yet read that far into OOSC, so this is going to be arguing
from a rather abstract understanding, but:

Does his model of person include a corporation?  Some cars are owned by
non-human "PERSON"s.  If a corporation owns a car, and assigns use of it
to, say, the General Manager's Office (which, in practice) turns out to
mean the General Manager, then is the habitual user-controller of the
car the owner?

I expect that any example given in OOSC will be an extremely simplified
form that doesn't map in any fully formed way onto reality.  Because of
this, I don't expect that it is reasonable to expect that the
"PERSON_ROLE" class would be introduced, UNLESS there was some
particular pedagogical point that it was needed to solve.  OOSC is a
learning tool, and therefore presents a limited picture of the world
with a focus on "easy to understand".  (The library example in the
earlier chapters wasn't very convincing, either, but it was a good tool
for making points with).
