As a Traffic Safety Specialist, this book is a MUST, this old book needs to be mandatory reading for any person interested in Road Safety, Ralph documented the resistance of car companies to the introduction of safety features, like safety belts, that looks timely today, for example with the lobby that produce a delay in the mandatory fitting of air bags. Also you will learn how the primitive road safety components, still used in USA, called the three E's (Engineering, Enforcement, Education ) was born as a device to direct the efforts to the community away from the real problems of safety of the vehicles, some of the that was sell with tires that don't resist the weight of the fully loaded vehicle !.
Finally you can understand the lacking level of road safety in US versus European countries that have in service safety policies that will reduce the absolute number of killed by 30% over 5 years.
This book is the necessary building stone to the effort to make car manufacturers accountable for the safety level of his products.
I can't understand why some publisher is not doing a new edition of it.
