There are many speculations about the circumstances and causes of the car accident in Jimmy Lin. Is this information credible? How to analyze objectively?

Jimmy Lin, a singer, actor and racing driver, was injured in a car accident. Due to brain injury, he was temporarily unable to repeat the accident. So all kinds of online speculation reports are true or false. Let me sort out the causes of the car accident in Jimmy Lin and make a logical analysis for reference only, not as a factual basis.

1, the speed of the accident is not fast, which is confirmed by three videos, one is the back surveillance video, the other is the opposite driving record, and the other is the front surveillance video released later. The speed is really not fast. The information of speed difference is credible √. Reliability 100%

2. Taiwan media reported that the traffic police said that the cause of the accident was a collision caused by "not paying attention to the situation in front of the car". According to the surveillance video, before the accident, the vehicle just turned around. After turning around, the vehicle quickly straightened its direction, but suddenly turned around near the scene of the accident. As a professional racing driver, even if he is distracted, he will react in time when the vehicle suddenly turns. When the direction changes, inertial force will appear, which is manifested as centrifugal force in the opposite direction, and even if he falls asleep, he can wake him up. Besides, in Jimmy Lin at that time, the police were unlikely to know the cause of the accident from Jimmy Lin, so they could only guess. Therefore, it is suspected that distraction caused the accident.

I found the source of the suspicious change, as follows:

The main picture is the Taiwan Province media mentioned in the report, and the green box is the police statement suspected of Taiwan Province media. The police guessed from the surveillance screen and turned it into a factual description in the media ... The credibility is 5%

Jimmy Lin didn't wear a seat belt. This has been confirmed by rescuers, and it should be credible not to wear a seat belt during rescue. But personally, I don't believe that he didn't wear a seat belt in the accident. There are two reasons: (1) His son is in the passenger seat, wearing a seat belt, and his son is also playing racing. At that time, he was about to take part in the go-kart race, so it was impossible for a father not to wear a seat belt just to set an example.

After the accident, Jimmy Lin was still conscious until rescuers arrived. At this time, his normal reaction should be to take his son out of the car, and unfasten his seat belt is 1 step, but his foot is stuck and he can't get out. I mean, whether he wore a seat belt or not, as long as he was sober after the accident, he would definitely unfasten his seat belt before the rescuers arrived. Therefore, it is doubtful that the seat belt was not worn when the accident occurred. Credibility 20%

4. Was automatic driving turned on when the accident happened? Jimmy Lin had experienced the auto-driving before and gave a high evaluation, so it was possible to start the auto-driving at that time. But now that the front of the car has been burnt down, whether to turn on the autopilot when the accident happens ultimately needs the driving data in the cloud or Jimmy Lin himself to confirm. It is a bit strange that the public response of the relevant personnel of the car factory did not mention any information related to the accident, which is different from their reaction to other accidents ... so it is still doubtful whether to turn on automatic driving. 50% confidence

(Note: Just like wearing a seat belt in front, we only discuss whether it is turned on, not whether it is related to the accident)?

5. Has the vehicle been modified? As a professional racing driver, it is said that Jimmy Lin is a car modification enthusiast. It is said that he had previously modified the pure electric car of the same brand to run on the track. There is no evidence that this pure electric vehicle used for daily transportation has been modified. However, although the relevant personnel of the car factory did not mention the cause of the accident in the interview, they stressed that there was no flammable substance in the front of the car, which means there was no lithium battery, so what was burning in the front of the car? Did you add batteries or other flammable materials? Judging from the final result, the main battery of the vehicle should not be ignited, otherwise it will not just burn a front.

Another detail is that when the crane lifts the fire-fighting vehicle, the flame comes out from the rear of the vehicle again, which also shows that the rear battery is still there.

But on the other hand, I also noticed that the position of the bottom of the passenger seat seems to be the first to smoke after the collision (see the first moving picture). Whether the battery is located in that position needs to be analyzed by people who know the car, but personally, I think that once the front battery pack burns, the rear battery should not be spared. Generally speaking, for safety reasons, drivers' seats, including passenger seats, should not be equipped with batteries ... In short, it is doubtful whether to modify them before Jimmy Lin is restored. 50% confidence

6. The picked-up mobile phone caused a car accident. I ruled this out as soon as I saw the headlines. I don't believe that a professional racer's chance of picking up his hand will lead to yaw, and neither will I if he is killed. ...

However, I saw the analysis of a cyclist "marco735 18" in the auto forum: I think it is most likely that Jimmy Lin dropped something on the ground, and he turned on the autopilot to let the computer take over the car to get it himself. But when he found he couldn't reach it, he unfastened his seat belt. He neglected one thing. When the seat belt was unfastened, he quit. At this time, the car continued to drive in the original direction. Lin may not have noticed that the autopilot quit, thinking that it would be okay to pick up things for a few seconds. As a result, there was a collision as soon as I picked up something and sat down.

If you are in a non-driving state, that is, you are not in a state of manipulating the steering wheel by yourself, it is really not easy to find yourself yawing in the process of picking things up, depending on whether the automatic driving system has obvious sound warning when exiting. Therefore, the collision caused by picking up the mobile phone in the state of automatic driving is possible.

However, some netizens reminded me that in the automatic driving state, the driver's foot is not stepped on the pedal, whether it is the accelerator pedal or the brake pedal, then when the vehicle exits the automatic driving, the vehicle will slow down under the action of kinetic energy recovery, which is obviously inconsistent with the situation in the video. Therefore, there is little possibility of an accident when picking up the mobile phone. Reliability 10%

The above is purely personal analysis, not as a factual basis, and the real situation needs follow-up investigation.
