如果没有的话，为啥要大规模召回和大笔罚钱？

 

The Firestone and Ford tire controversy was a period of unusually high failures of P235/75R15 ATX, ATX II, and Wilderness AT tires installed on the Ford Explorerand other related vehicles.

The tire failures are linked to 271 fatalities and over eight hundred injuries in the United States with more injuries and fatalities occurring internationally,[1][2] it led Bridgestone/Firestone and Ford Motor Company to recall and replace 23 million tires.

General Motors will settle with 124 families over deaths resulting from faulty ignition switches that were installed in the 2.6 million small cars recalled last year, including the Chevrolet Cobalt and HHR, Pontiac G5 and Sky, and Saturn Ion and Solstice.

• 这些和统计无关。如果你想从中推出“买辆福特车会爆胎的概率”或者“买辆GM车会打火松动的概率”，那么没有统计意义。 -QuantPM- ♂ 给 QuantPM 发送悄悄话 (0 bytes) () 10/17/2017 postreply 10:35:01

• 如果想再从“丰田某某事死x人，x<271”推出“丰田比福特好”，就更没有统计意义。 -QuantPM- ♂ 给 QuantPM 发送悄悄话 (0 bytes) () 10/17/2017 postreply 10:38:17

• 假如在福特和GM召回前你看到了以上数字，vs.另一个0死亡率的，你买哪个？ -basicenglish- ♂ 给 basicenglish 发送悄悄话 basicenglish 的博客首页 (3123 bytes) () 10/17/2017 postreply 10:41:56

• 我今年1月买新车，按我的预算，安全性考虑，理性地选了Escalade ESV。之前是两辆GL开了10多年。这种数据不在考虑之列。 -QuantPM- ♂ 给 QuantPM 发送悄悄话 (0 bytes) () 10/17/2017 postreply 11:10:54
