回複：很多不懂汽車設計的人總把追尾拿出來比較，這是大大的錯誤的！

汽車的前麵設計和後麵設計的理念是完全不一樣的：

前頭要考慮各種碰撞，如 high-speed and low speed, ncap, iihs, 現在還要考慮碰行人的安全性。所以前頭有crash zone. 不幸的 radiator 又要在前頭散熱，所以碰下來，肯定是一地 coolant. 但是隻要人沒事，設計的初衷就達到了。

車後頭有油箱，所以要保證碰撞不能造成油箱變形，因此不會有 crash zone, 而是保證將力通過結構剛性傳到前頭，所以變形不會很大。

再者，前頭碰撞基本上是本車在動，很多時候是高速前行，然後在0.1秒中fully stop. 而後頭碰撞往往是被碰，從速度為零，在更長的時間中加速到（被推動）到10邁以下的速度。這兩個對車子的 structure integrity 完全是不同的測試。不可以就以此的結果來比較兩車的安全性。It's not apple to apple comparison!
