When the dollar value of the damage done to the vehicle is probably greater than the fine for ending another's life, yes, there is some concern for justice.  I suspect we agree that there was no intent to cause this accident, and that many comments want to inflict harsh penalties where no intent to cause harm was present. 

The problem is that someone operating a powerful vehicle (a ton or two of metal at speed) should be able to anticipate events or at least react appropriately to the unexpected.  If you do not believe that is possible, then we disagree on the ability to train and prepare people for eventualities. 

The want of testimony from the accused leaves me wondering whether the unfortunate, unavoidable accident wasn't really an easily averted event cause by the lack of consideration for the rest of the world in general, or for a woman and  her family in particular.
