看过一篇文章分析大小车的安全性的,里头也是提到实际交通事故的撞击方式,在所有致命事故里,50%涉及非两车撞击(翻车,撞击障物,比如树,水泥柱子),这类事故里跟安全相关的因素车子重量大小不算其中,主要是$ {, C+ f$ M; c. U

None of these items are automatically better in large and heavy vehicles. In fact, for item c, the roof of a heavier vehicle is more likely to be crushed in a roll-over accident than a lighter vehicle. This is one reason why rollovers in SUV's cause a higher percentage of deaths than in cars (in addition to their higher center of gravity.): B% Q9 X0 M! k, e2 V0 r
