争论来源就是官方推特
"There is no safer car in the world than a Tesla"

之后隔天就陆陆续续有NHTSA和美国政府出来澄清的新闻

简单讲，去年10月Tesla官推讲没其他车比model3安全，
NHTSA隔天马上发澄清稿五星分级外没有谁更佳的说法
因为NHTSA仅对测试结果评定星等1~5，同样星等内没有实际排名
但Tesla拿NHTSA资料去，弄个排名，说没有车比Tesla安全
这也不是第一次，2013年Elon Musk讲5.4星被NHTSA纠正过一次

: 原文内容：
: Last October, the NHTSA, the federal agency that (among other things) does saf
: ety crash tests wrote a letter to Tesla, telling them not to say things like
: “Model 3 achieves the lowest probability of injury of any vehicle ever tested
: by NHTSA” and “But when a crash happens in real life, these test results sh
: ow that if you are driving a Tesla, you have the best chance of avoiding serio
: us injury.”? Car companies who do the tests have to follow regulations about
: how they express the results, and NHTSA says Tesla’s marketing breaks those r
: ules, and ordered them to stop. Tesla said they won’t stop — I’ll get into
: why they would be this defiant below.
: When NHTSA does a test, they slam a car into walls and barriers.? They calcula
: te a score based on, among other things, how the crash test dummies come out o
: f it. The Tesla Model 3 did indeed get the best score ever, and this is part o
: f why I bought mine.
: NHTSA doesn’t want Tesla saying those claims because it declares that the num
: bers can’t be compared between cars that are very different in weight.? That
: even if the test did indicate that you would do better in a Tesla Model 3 than
: any other car hitting a wall, this might not be true if your Tesla crashes in
: to a safely designed Hummer or even an unsafely designed transport truck.
: In boxing, they sometimes try to judge boxers on what they call a “pound for
: pound” comparison, trying to score them independently of their weight. Mostag
: ree that Sugar Ray Robinson was, pound-for-pound, a much better boxer than Mik
: e Tyson. But if you had to bet on one in a fight, you would probably bet on Ty
: son.
: Tesla notes that the Model 3 is heavy as cars go, and it is, because of its ba
: ttery pack, but it’s still not a truck.
: NHTSA is not saying the Tesla isn’t the safest car ever.? Rather, they are sa
: ying, because their tests can’t be used to compare cars of very different wei
: ght, they don’t have the answer to that question, and Tesla should not imply
: they have said this. They’re right, and probably have the legal authority
: to demand this. But Tesla’s score is very impressive, and very likely means t
: hat “pound for pound” it is the safest car made so far, and the safest of an
: y car, regardless of weight, in a crash against a stationary object. That’s s
: omething to be proud of. And while NHTSA says their scores are not approved to
: be compared between weight classes, that doesn’t mean that it might be possi
: ble to do so.
: So why would Tesla defy NHTSA on this, and not simply come up with more subtle
: ways to say their message? I have a cynical suspicion that they don’t mind a
: ll the press this battle has generated; you’re reading some of that press now
: . It’s a nice thing to see tons of press about the very fine points of how yo
: u define “safest car ever” and who can say what, because the main thingleft
: in the mind of the public is a very positive message for Tesla.
: 重点翻译：
: NHTSA 的撞击测试是用一面墙，然后根据撞击的结果来算出一个分数。Model 3 的确拿到
: 了有史以来的最高分，那为什么 NHTSA 不希望特斯拉主张 Model 3 是有史以来最安全的
: 车呢？因为实际车祸不会只是撞一面墙，有可能撞到一台安全性也高的悍马，或是一台根
: 本不符合安全规定的改装货车，这都有可能让 Model 3 撞击结果不符合测试结果。
: 用拳击来比喻的话，可能一个轻量级的选手拥有有史以来最好的数据，但对上一个数据稍
: 低的重量级选手，你可能还是想赌后者赢。
: NHTSA 并没有直接否认“Model 3 是有史以来最安全的车”这句话，而是说他们的分数不
: 能拿来比较重量差很大的不同车款，所以他们不希望特斯拉这样比较。
: 但是特斯拉也没错，不管是跟同重量级的车比较，或是跟不同重量的车只比撞墙，Model
: 3 的确就是最安全的车。
: 作者另外还怀疑，特斯拉刻意继续这样比较的原因是这类的报导让 Model 3 跟“有史以
: 来最安全”这个关键字持续曝光，当作免费的正面宣传。
: 心得/说明：(30字以上)
: 所以说 Model 3 是有史以来最安全的车并没错
: 但是以 NHTSA 的立场 应该要加上两个条件
: 1. 只跟同重量级车比
: 2. 跟不同级车比 只比撞墙
: Model 3 如果撞上火车 当然还是火车比较安全
: 但是跟同级车比它的确是有史以来最安全
