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) a strong cabin area that does not collapse in the crash9 c, U- X4 @0 {. t; f5 m
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.)- `1 D2 H& c p6 q2 G

而在涉及两车相撞的另50%致命事故里,70%是侧撞和追尾,这里a和c是主要安全因素,车子质量仍然无关。下面的图表反应了这类碰撞时不同品牌车子的安全状况
