[冷知識分享] 遇到交通意外，跳車逃生時應該向前跳還是向後跳比較安全呢？

遇到這麼緊急的情況，生死攸關，千萬不能做錯決定，假如你決定朝車子行駛的方向跳出去的話，你實死無生，因為離開車子的身體會循「慣性法則」隨著車子的速度向前，身體會加速，然後狠狠的摔在地上，如果向後方跳的話，速度會相對抵消，著地時會減少一些撞擊力道。此外，向前跳的話，著地的時候，身體會向後仰，後腦撞到的危機性較大，死亡率亦較高。

If you are carrying a forward momentum and when the body/ object landed, the
momentum will continue its direction unless affect by other external force. (Baisc公仔箱論壇" p1 r Z& I9 T) D3 ]+ Q& C* z3 ]

the ground first unless you lean back when you jump off the moving object.
