NHTSA tentatively decided not to require the installation of automatic-reversing features on power windows because 50-75% of the approximately 6 deaths/year will be prevented by the safer pull-up switches mandated as of October 2008. The cost of $6-12 per window is unjustified.
Background
Auto-reverse windows would cost automakers $6-12 per window
NHTSA uses $6.1M as the cost of a “statistical life” when determining cost-effectiveness
