一百万highlander卷入事故的可能有一千，那么死了10个人，死亡率是百分之一。
一百万blazer卷入事故的可能有2万，那么死了200个人，死亡率依然是百分之一。
Let's assume the above condition, this means to me that:
highlander may have a better maneuverability than blazer to avoid trouble. And this should be considered
when comparing safety score between cars.
Just propose a extreme case:
A heavy tank style car with zero maneuverability is more dangerous than a nimble mini-cooper
Of course, if you only consider the damage after crash,
you have your point. But my humble opinion is that
safety score should consider both the structure strength and manueverability
maneuverability may be
