Tesla's latest annual report came out, and the words were full of words:
"Can't figure out that there are still people who don't buy Teslas"...
Why?
The report cites data from all sides to prove that Tesla is both safe and environmentally friendly, such as autonomous driving, which is 8 times lower than the accident rate of human drivers:
In terms of active safety, Tesla also directly named competitors to compare with each other:
Not long ago in Beijing, there was a major accident in Beijing where the owner of the Tesla accidentally stepped on the acceleration and caused a 4-car collision at a speed of 170 kilometers per hour, and the owner initially said that the "brake failed", and then admitted that he had made a mistake in operation.
Tesla also disclosed for the first time in this report that it has taken proactive safety measures against this kind of human error.
In addition, oil car fans criticized the problem of tram fires, and Tesla also came up with data to prove that the probability of fire of its own products was 11 times lower than that of traditional cars:
Where does Tesla's conclusion come from, and how is Tesla's interpretation of the definition of vehicle safety different from that of traditional car companies?
Autopilot is 8 times stronger than humans, where is it?
The so-called "8 times stronger" is based on the latest statistics from NHTSA (National Highway Traffic Safety Administration) in 2021.
The first is how many miles on average when Autopilot is activated into an accident.
Then there's the average number of miles recorded by Tesla owners longitudinally and without Autopilot, and a lateral comparison with the same data from NHTSA in the United States.
Tesla said one accident was recorded for every 4.54 million miles (7.26 million kilometers) with Autopilot activated, which includes auto-assisted driving and active safety features.
Tesla owners who did not turn on Autopilot and turned off active safety features had an accident on average every 1.3 million miles (2.08 million kilometers).
Also in 2021, NHTSA recorded an average of one traffic accident per 550,000 miles (880,000 kilometers) in the United States.
The so-called 8 times is the comparison between Tesla's Autopilot and the average accident rate in the United States.
The statistical object does not include FSD, the essence is still the assisted driving level Autopilot, and Tesla also believes that the statistical results are conservative.
Tesla claims to be rigorous, including car accidents that deactivate autopilot within 5 seconds of each impact, as well as every car accident with an airbag popping open, even if it is a rear-end accident without responsibility.
The NHSTA's accident statistics never count small accidents, and Tesla believes that at least half of the accidents are missed.
That said, the molecules can actually be larger, and Autopilot's reliability may be far more than 8 times higher than the national average.
Where such data comes from, Tesla explains from 3 aspects.
The first is the active safety functions of the vehicle itself, such as automatic emergency braking, lane departure warning, forward and side impact warning, obstacle recognition and so on.
We are all familiar with AEB, ACC and crash warnings, but Tesla has revealed a unique active safety feature for the first time:
Mechanism for remediation of wrong pedaling.
If the camera recognizes that there is a very close obstacle in front of it, and the driver quickly and deeply steps on the accelerator pedal, the system will determine that it is a mistake, and then instantly cut off the torque output of the motor to ensure safety.
Tesla says the feature prevents hundreds of accidents every month.
Tesla's so-called "brake failure" accidents may also be reduced accordingly.
Behind the active security function is Tesla's emphasis on data-driven functional iterations.
At present, more than 2 million vehicles on the road around the world continue to transmit measured data back, which is far larger than any autonomous driving company.
This also enables Tesla to find complex scenarios that are difficult to cover in ordinary autonomous driving tests and regulatory standards, so as to give targeted solutions.
After accumulating enough data, the Autopilot system improves the accuracy of accident prediction, and can tighten the seat belt to trigger the airbag before the collision occurs.
Finally, Tesla also cited passive safety data. For example, the body center of gravity is lower, and there is no front-mounted engine, making Tesla more like a fuel car with a mid-engine.
The benefits of this not only increase the overall agility and handling of the car, but also minimize the rotational kinetic energy of the horizontal axial direction and improve body stability.
In addition, in terms of body structure, Tesla has also made specific enhancements for common types of collisions.
As for the effect, Tesla said the Model 3 and Model Y both received 5 stars in all USNCAP categories:
Vehicle safety, tesla also emphasizes something
Regarding safety, tesla not only cites three-party data proofs, but also uses this report to illustrate some of its own understanding.
For example, Tesla has caused controversy because of the airbag problem before, and this time Tesla specifically explained in the report why the airbag did not pop out in some accidents.
For example, in such a common "lateral overlap" collision accident, the previous sensor design can usually only detect forward collisions, and the perception of lateral collisions is insufficient.
Therefore, Tesla later improved the placement and type of airbag sensors, so that Tesla can detect almost all types of collisions.
At the level of battery safety, in the past, oil truck fans often criticized the tram for being prone to spontaneous combustion, which has become a hidden danger to dissuade many users over time.
However, Tesla came up with data in the report to prove that although fire accidents cannot be completely avoided, Tesla's fire accident rate per 1 billion miles is 11 times lower than the comprehensive data of all cars in the United States:
In addition, Tesla also emphasized the effectiveness of its own security configuration.
With the same active security configuration, Tesla gives users better actual protection.
In the case of AEB, almost all cars are now standard, but the range of sensors and the underlying computing power are very different.
Tesla's active safety features are guaranteed by eight cameras, a neural network, and a complex electromechanical system, and AEB performance is more than 45% better than the common vision + radar fusion solution.
In the IIHS (American Highway Safety Insurance Association), Euro NCAP (European New Car Safety Evaluation Organization), ANCAP (Australian New Car Safety Evaluation Organization) and other three-party tests, they have received extremely high scores.
In summary, Tesla officials want to explain that their models pay attention to safety, reasonable design, and the conscience of materials.
However, Tesla did not say clearly, is that the owner continues to contribute road data, each accident has enriched the Tesla database, in fact, did Tesla volunteer road testers and safety experiment materials.
So, is Tesla Autopilot today safer than it was yesterday?
Foreign media insideevs made detailed statistics.
All the data comes from Tesla's official statistics, and the data means that an accident is reported every XX mile, so the higher the point in the y-axis direction, the better.
Whether Autopilot is reliable or not, whether there is progress, you should have the answer.
There has always been a constant controversy about Tesla's safety, whether it is spontaneous combustion, autopilot, brakes... As long as there is an accident, Chinese and foreign public opinion will inevitably pay close attention to it, and divide into black factions and upright factions that are fiercely opposed.
Both views are very simple and direct, nothing more than "unsafe cutting the owner's leeks" and "really safe car owners touching porcelain"...
What does Tesla officially think?
Intriguing statements appear in this report:
Tesla said that in order to attract attention, the media usually only reports on the fire of the tram, and does not mention the spontaneous combustion accident of the fire of the traditional fuel vehicle.
In fact, musk himself sent 3 tweets in February complaining about public opinion's treatment of Tesla's "double standard":
"More than 1 million gasoline cars are on fire every year, resulting in thousands of deaths, but none of them have made headlines like a Tesla car fire. That's a problem. ”
Do you think Musk is justifying the Tesla accident, or is public opinion really unfair?
One more thing
In the Tesla report, the job and treatment are also disclosed.
Tesla received more than 3 million job application resumes in 2021, and according to The Universal's 2021 survey, Tesla and SpaceX ranked the top two job units for science and engineering graduates in North America.
So what about Tesla's treatment?
Tesla did not disclose the specific amount of salary, but introduced a stock-based employee compensation system.
Suppose an employee receives an incentive of 320 shares of Tesla stock in 2018 and can sell 20 shares per quarter for 16 quarters (4 years).
The employee's actual profit comes from the stock spread at the time of the sell-off, calculated according to Tesla's stock price in early 2018, and by the beginning of 2022, the employee had an average of $14,113 (94,000 yuan) in income per quarter in addition to salary.
Employees can also purchase additional stock at a discounted price through the stock purchase program.
Equivalent to making at least nearly 400,000 more a year, how are you moved?
