Indeed it does, and "national" characteristics (as that undoubtedly is what inability to accept loss of face may be characterised as is in many cases) is part of the reason that we DO differentiate between accidents depending on the nationality of the parties involved. To do so may be "politically incorrect", but to fail to do so is to be blind to the fact that we are indeed all "different" in ways that are both good and bad. Unfortunately, these days it is seen as a crime to say so, but we don't all react the same, and we shouldn't pretend otherwise.
