BPF, try the surprise of finding out Canadian commercial licence holder (albeit helicopters) had no clue about the meaning/importance of hold short lines.
That's after trying to bust it 30% down the runway, impatiently trying to cross, with C150 after touching down and rolling. OR, thinking it's OK to hover within hold short lines at single runway GA airport with bizjet touching down shortly afterwards (turbulence hazard).
Yeah man, I do get why some Europeans or Australians have certain attitude towards FAA and US based pilots, but I had plenty surprises as junior instructor while back. Not implying Canadian system's bad, but if some people are slipping through 'net' of education and more, well, not so certain.
We all forget this or that, obscure information crammed for theory exams (me myself, going through European ATPL theory/question banks), but some things cannot be forgotten without suffering amnesia.
