Hello, I'm Yue Youzhi-John.
Yesterday morning morning rush hour, Shanghai Jiamin elevated north to south near the Yindu exit of a 4-car rear-end traffic accident, from the scene photos, the first two cars damaged is relatively light, it is suspected that the last Tesla Model3 due to the front car BYD Song Pro sudden braking and too late to react, Tesla directly shoveled the front BYD from the rear, and the two vehicles in front, the incident was at the rush hour, so that the right two lanes of the road were affected.
In a WeChat group conversation obtained by the auto industry's attention, the suspected Tesla owner shared some pictures, videos and details about the accident. The owner said that at that time, he used the Tesla automatic auxiliary driving system Autopilot, the speed of about 80km/h, with the car set to 1, but also opened the vehicle's front impact warning function, the owner tried to slam on the brakes when the accident occurred, but eventually due to the speed of the accident accident. Judging from the photos of the accident scene, Tesla lifted BYD from the rear of this point of view, one is that the rear of BYD Song Pro is too high, and the other is that as the Tesla owner said, the driver has vigorously stepped on the brakes during the driving process of the vehicle, causing the vehicle to lean forward instantaneously, these two reasons make Tesla find the opportunity to drill into the bottom of the front car, and the two direct collision vehicles, the air bags are not popped out, or because the contact surface of the two does not produce a large enough frontal impact force to trigger the airbag to pop.
In the final analysis, the accident was caused by Tesla's over-sticking with the car, fortunately, the owner also adopted the emergency brake disposal method in a very short period of time, reducing some impact and not causing serious consequences of injury to personnel. Tesla's distance function with the car distance can be set Oh 1-7, the vehicle will be based on the current speed and the front car to maintain a braking distance of 1-7 seconds, theoretically when the vehicle stops, the current vehicle and the front car will maintain a distance of about one parking space, of course, this is only theory, just as this accident is so, if the front car suddenly brakes, then this theory calculation in the face of the accident does not have much meaning.
On January 17, Tesla shareholder Ross Gable tweeted, "Since the launch of the fully automated driving (FSD) beta version for a year, there has never been a traffic accident in the vehicles participating in the test, which fully proves the professional caution of the driver and, more importantly, shows that the FSD system is completely safe." Tesla CEO Musk then retweeted the passage and affirmed the assessment: Really, really.
Tesla's auto-assisted driving system, Autopilot, is currently Tesla's standard configuration, which only provides assisted driving with limited automatic steering, acceleration and braking in the lane under the condition of active driver monitoring. The FSD name is full autopilot, Tesla from 2020 to the United States car owners to provide this fee software services, FSD initially sold in the United States $5,000, after several price adjustments, has gradually risen to the current $8,000, you can also use the monthly subscription method to rent this service, which is one of Tesla's charging growth points, compared with Autopilot, FSD has a more powerful autopilot function.
Tesla almost defines the ceiling of electric vehicles, and autonomous driving can be said to be the soul of electric vehicles, which is also one of the selling points that attract many Tesla supporters. People are eager to get smarter and safer intelligent driving systems, musk said in a recent interview that FSD has the potential to achieve L4 self-driving level by the end of this year. Tesla maintains a rapid iterative upgrade to develop and upgrade this system, but in the latest version, Musk is not very satisfied with its performance, Tesla also pointed out that FSD10.2 still has serious safety problems, it is recommended that owners do not rely entirely on FSD for driving. These serious safety issues include driving directly to the opposite lane at complex intersections, lack of close-range passers-by identification of driving routes, sudden withdrawal from FSD during driving, and sudden changes in driving routes at critical moments. The National Highway Traffic Safety Administration (NHTSA) has been paying attention to Tesla's FSD features since 2019, especially for some publicity that seems to imply L4 level, FSD, then the potential risks of Autopilot can also be imagined.
A few days ago, a Tesla owner in California was officially sued for a car accident caused by 2019. The U.S. Highway Safety Administration NHTSA investigation said that the owner used Autopilot at the time of the incident, the vehicle ran a red light and crashed into another moving vehicle, resulting in the death of 2 people in the hit vehicle, this case made the owner the first Tesla Autopilot user in the United States to be prosecuted for a felony. NHTSA particularly emphasized, "Once again, all car owners are reminded that none of the current commercially available vehicles can drive themselves autonomously, and whether or not the Level 2 assisted driving function is activated, owners must be in control and keep their attention at all times." ”
Ideal Car CEO Li Xiang once said that L2, L3 and other terms, users can not understand, suggest a unified name: L2 = assisted driving; L3 = automatic assisted driving; L4 = automatic driving; L5 = driverless, a redundant Chinese word should not be. He also suggested avoiding exaggerated publicity that would cause misunderstandings about user use.
Even so, some users of electric vehicles will also be accustomed to using these different degrees of auxiliary driving functions, and some potential risks to relax their vigilance, technology can of course bring convenience to a large extent, from the overall point of view, the risk of cold and cold is a probabilistic event for the group, and in case it falls on individuals, some results may be irreparable. Today's owner in Shanghai, or will be in awe of today's accident, whether it is self-driving or automatic assisted driving will remain careful to drive.
