I lean towards what Claude said,but for a somewhat different reason, not that his reason is essentially spot on.
I just don't like making big deals over things when it is not really necessary. ND like auto accidents happen.
They are almost always the result of someone doing something they should not have done, but we don't have enough jail space
to deal with everyone who causes an auto accident in which another gets harmed. We let the civil system take care of most
of that stuff. A true ND, is a "learning experience." Thank your personal deity no one got harmed and move on.
