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.)# P7 b) M# x! k6 s

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
