"Michigan repealed the mandatory helmet law for motorcyclists several years ago, and the annual rate fatality from motorcycle accidents has quadrupled since. That statistic doesn't seem to change some people's minds though. "

But possibly the number of quad and paraplegics went down along with spinal injuries, therefore reducing mandated costs to all others.............?
If you're dead, the costs are fixed and not ongoing for a lifetime.
