Got to preface this by saying that I live in a country where the postman
delivers mail to the door and it rarely snows enough to need serious
ploughing so take this with a pinch of salt. Anyway, it seems that
figures 12 and 13 of the moh.pdf address the problem with a cantilever
design. It should be possible to include a detented pivot in Figure 12
to take smallish knocks short of total contact. It would be possible to
mount the upright in a solidly fixed socket in the ground allowing the
post to be lifted out and replaced after the (inevitable) collision. The
KeeKlamp type of construction in Figure 12 allows for modular repairs.
