How does the fact that a driver may have caused an accident affect a crashworthiness action?

The doctrine of crashworthiness centers around the enhancement of injuries caused by a motor vehicle defect. The issue becomes whether the defect increased the injuries, and fault of a person injured does not prevent recovery on a crashworthiness action. The fault issue may arise when the court or jury weighs the comparative fault of the individual causing the accident with the fault of the manufacturer, so that a reduction in the amount of damages you are entitled to may result.
