回复：很多不懂汽车设计的人总把追尾拿出来比较，这是大大的错误的！

汽车的前面设计和后面设计的理念是完全不一样的：

前头要考虑各种碰撞，如 high-speed and low speed, ncap, iihs, 现在还要考虑碰行人的安全性。所以前头有crash zone. 不幸的 radiator 又要在前头散热，所以碰下来，肯定是一地 coolant. 但是只要人没事，设计的初衷就达到了。

车后头有油箱，所以要保证碰撞不能造成油箱变形，因此不会有 crash zone, 而是保证将力通过结构刚性传到前头，所以变形不会很大。

再者，前头碰撞基本上是本车在动，很多时候是高速前行，然后在0.1秒中fully stop. 而后头碰撞往往是被碰，从速度为零，在更长的时间中加速到（被推动）到10迈以下的速度。这两个对车子的 structure integrity 完全是不同的测试。不可以就以此的结果来比较两车的安全性。It's not apple to apple comparison!
