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.)- D& J( d! f% N 9 c1 J) x% e0 o0 V) H: t; S: L# H9 ]2 _7 Z$ p& c
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 9 x! @. k: m# ^% P9 b( u# Z6 D8 fInsurance Institute for Highway Safety (IIHS) are shown below. (see http://www.iihs.org/ratings.)! F* t& [$ |2 D/ r
