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.
