This argument? Which exactly? There are multiple to choose here, and I&#x27;m not seeing how they apply to motorcycle helmet laws.<p>In any case, the helmet discussion is a silly one. You wouldn&#x27;t argue that the victims in a school shooting should have been wearing bullet-proof vests. I mean, I&#x27;m sure there are studies on the remarkable efficacy of bullet-proof vests when faced with bullet impact, and clearly everyone of us should wear one. But we don&#x27;t, because we fully understand that a much more sane course of action is to make sure <i>there are no high-powered bullets hitting school kids</i>.<p>Similarly, when faced with the impact of a 2 ton car at speed into squishy flesh it is a hopeless task to effectively diminish the forces involved with a piece of styrofoam. The clear factor in traffic mortality is the presence of machines with enough power to satisfy the electricity demands of a suburb street. There is no solution that doesn&#x27;t involve eliminating the source of danger.
