Sure, all the low-hanging fruit is gone. It&#x27;s a lot easier and cheaper to cut fatalities by X% by installing three-point seat belts in every car than it is to do it by building advanced stability control systems.<p>But still, the returns are still significant and the dangers are still huge. I&#x27;d guess that your tremendous backlash comes from using a deeply misleading graph as the foundation of your comment and from the strong implication that additional safety improvements are no longer worthwhile.
