"IIHS researchers compute the rate at which drivers of individual models are killed in crashes." Driver death rates by make and model
One way to compare the relative safety of vehicles is to look at driver death rates. From time to time, IIHS researchers compute the rate at which drivers of individual models are killed in crashes. Rates are given as the number of driver deaths per million registered vehicle years. (A registered vehicle year is one vehicle registered for one year.) To increase the exposure and thereby improve the accuracy of the calculations, results are included for the previous three model years if the vehicle wasn't substantially redesigned during that time. These calculations take into account only deaths of drivers, not passengers, since every vehicle that crashes has a driver, but not every vehicle has passengers.
FARS data are obtained solely from the state's existing documents:
Police accident reports State vehicle registration files State driver licensing files State highway department data Vital statistics Death certificates Coroner/medical examiner reports Hospital medical reports Emergency medical service reports Other state records The following facts are based on analysis of data from the U.S. Department of Transportation's Fatality Analysis Reporting System (FARS). Fatality Analysis Reporting System
Fatality Analysis Reporting System (FARS), which became operational in 1975, contains data on a census of fatal traffic crashes within the 50 states, the District of Columbia, and Puerto Rico. To be included in FARS, a crash must involve a motor vehicle traveling on a trafficway customarily open to the public, and must result in the death of an occupant of a vehicle or a nonmotorist within 30 days of the crash.
National Highway Traffic Safety Administration (NHTSA) has a cooperative agreement with an agency in each state's government to provide information on all qualifying fatal crashes in the state. These agreements are managed by Regional Contracting Officer's Technical Representatives located in the 10 NHTSA Regional Offices. Trained state employees, called "FARS Analysts," are responsible for gathering, translating, and transmitting their state's data to National Center for Statistics and Analysis (NCSA) in a standard format. The number of analysts varies by state, depending on the number of fatal crashes and the ease of obtaining data.
FARS data are obtained solely from the state's existing documents:
Police accident reports State vehicle registration files State driver licensing files State highway department data Vital statistics Death certificates Coroner/medical examiner reports Hospital medical reports Emergency medical service reports Other state records
From these documents, the analysts code more than 100 FARS data elements. The specific data elements may be modified slightly each year to conform to changing user needs, vehicle characteristics, and highway safety emphasis areas. The data collected within FARS do not include any personal identifying information, such as names, addresses, or social security numbers. Thus, any data kept in FARS files and made available to the public fully conform to the Privacy Act.
Each analyst enters data into a local microcomputer data file, and daily updates are sent to NHTSA's central computer database. Data are automatically checked when entered for acceptable range values and for consistency, enabling the analyst to make corrections immediately. Several programs continually monitor and improve the completeness and accuracy of the data. The FARS data file used for the statistics in this report was created in July; however, this FARS file will officially close when next year's data are released. This additional time provides the opportunity for submission of important variable data requiring outside sources, which may lead to changes in the final counts. The updated final counts for this year will be reflected in next year's report.1
活菩萨啊!
可从车祸死亡数据看,丰田安全明显好过美系,咋回事呢?
4.35% of kobe Steel 's products go to Toyota.
No other companies used more than 1.65%
而且统计方法很有问题,里面猫腻大呢。

要想理解“统计意义”,请学学null hypothesis,p value。NHTSA没有公布这些,学术上就叫没有统计意义。
买车考虑安全性不看实际车祸死亡的数据,看什么?听一家之言么?
本田因隐瞒伤亡事件在美遭罚7000万美元
算法都给出来了。至于是不是“正确”,请参考博弈论对MINIMAX策略的阐述、分析。
就没提厂家自报

很有意思,日本和德国都是自己的车子很少有外国车。死亡率都没有美国高。
日本和德国比, 考虑百万人口拥车数,人口密度以及行车密度后, 没啥好坏差别,很近似。
不给出方差、p值等细节数据的报告是不能随便做减法比较大小的。
一个比较舒适, 操控性比较好的车, 卷入单车死亡的概率就会低。
像Dodge Challenger, 就是个赛车, 或者司机认为它是个赛车, 把它当赛车那样去开, 单车事故率就会高许多。
不同的司机对车要求也不同。 我在高速上特受不了路噪音。 马上会昏昏欲睡。 所以开像RAV4, CRV那种车我是不敢上高速的。
洗涤真是不遗余力啊
