楼上二位是不是看反了？？？原文说..hitch..reduced damage(车的)增加了risk of whiplash b

第一段就说:

Today, roughly 40% of the vehicles on the highway have receiver hitches – and although they are necessary for towing – they reduce rear end collision damage and INCREASE the risk of whiplash by creating a stiff "crash pulse".原因是hitch导致更硬的碰撞脉冲

第二段

In a European study by Chalmers with data from Folksam and Autoliv they concluded that a vehicle equipped with a receiver hitch (tow bar) increases the risk of whiplash by 22% if it is hit in the rear. ...

后面解释说In a rear end collision involving a vehicle equipped with a receiver hitch, the crash energy is transferred directly to the frame of the "target" vehicle and then to the occupants.  碰撞能量直接传递给目标车的车架结构然后是乘客身上。

因为bamper之类是吸能的，而hitch等却不是，

所以文章又说 

So having a vehicle equipped with a receiver hitch is a huge liability when it increases your risk of whiplash by 22% - especially when women and children are already two times more likely to get injured from whiplash then men (their necks are not as strong

Your insurance company will argue that since there is little damage to your vehicle, you could not have been injured – and that couldn't be further from the truth. 

而对保险公司是双赢之局：即可以少修你的车，也可以少修你的人（车的损伤小，你的claim也更不容易批）

所以，根据该文章，没事别加hitch，对自己没好处，只是减少点车的损害
