The MUARC has a lot to answer for regarding these statistics that they publish. I know a few of the students in the Monash Uni Auto/Mech Engineering course, and each one of them has told me that is you want to work in that center, you have to subscribe to the philosophies contained in their briefs to the government, and that an opposing view (i.e. fatigue, lack of knowledge/concentration, conditions being causes) will get you removed very quickly.
This line could be applied to global warming as well, it has long been used to justify government spending and to control the actions of the general populace, consider the fear of MAD and the Red Threat, this managed to keep the population fearful and looking towards the government to provide for them, rather than being self responsible. If the government can make the population totally subservient to themselves, then they have won.
