 Topsy-Turvy US Safety Policy Continues to Kill Thousands of Road Users

(or The Dramatic Failure of U.S. Safety Policy Revisited)

Auxiliary information: Revised 1 December 2012 - China data deleted from study due to uncertainties about reliability.

This Presentation is based on one I delivered to The Eye and The Auto International Conference, 2011-09-(1214), in Detroit MI, organized by the Detroit Institute of Ophthalmology.  In Traffic Safety (2004), the chapter titled The Dramatic Failure of US Safety Policy concludes that US Safety policy, by rejecting science, ends up placing most emphasis on where benefits are least (JAMA reviewer calls this Chapter the Showstopper).  The conclusion that disastrous US policy was killing more than ten thousand additional Americans every year was based on comparing US performance with that in three Comparison countries (Britain, Canada and Australia).  This present presentation compares the US to 27 countries, and for each of them 7 years more data than available in the earlier study.  The presentation shows the data for each country in a separate graph.  The enormously greater amount of data adds vastly more support to the earlier conclusions.   Namely, (1) US safety performance is dramatically worse than that in other industrialized countries. (2) The fatality declines among other countries are similar and define what is normal. Their policies emerge from imperfect legislative bodies whose members are much concerned about being reelected. The far from optimal policies that emerge are ordinarily foolish. (3) US policies are not ordinarily foolish. They are extraordinarily foolish. (4) This is because US safety policy continues to maximize litigation earnings and the resulting political contributions (for example, Toyota "phantom acceleration") while ignoring science, knowledge, or even common understanding. This results in placing priorities almost perfectly opposite to where safety benefits are greatest.
