Ke Xue: Shinichi and I are childhood friends

While Michida Junko was asking about the situation, the identity of the driver of the red car was also found out.

Although the red car was severely damaged, the license plate was still recognizable. After investigation, the identity of the owner was known. His name was Hayami Hayabusa, and he was a manager of a foreign trade company.

At the same time, the surveillance at the intersection was also called up.

The surveillance was a bird's-eye view, and it can be clearly seen that the two cars did not slow down when approaching the intersection. It was not until they entered the intersection that the green car braked obviously, but it was too late. The two cars collided directly.

After that, the green car crashed into the billboard, and the red car flipped directly into the river.

Yuya was watching the surveillance, and Michida Junko suddenly came up: "Detective, did you see anything?"

Yuya touched his chin and said: "Collision Course, collision course phenomenon?"

"Yes, I think this is it!" Michida Junko nodded repeatedly.

The so-called collision route phenomenon is that two cars approach the intersection at right angles at the same distance and speed. At this time, the two cars and the intersection on the plane form a 45° isosceles triangle;

Human vision is divided into central vision and peripheral vision, and it is difficult to identify small moving objects in the peripheral vision. In other words, at this time, the cars are in the blind spot of both parties' vision, so they cannot immediately find the other car. Therefore, when neither of them notices the other car and enters the intersection without slowing down or stopping, they will collide.

This kind of accident often occurs at intersections with good vision and straight routes.

"That's right," Michida Junko nodded repeatedly, "I think so too. You are worthy of being a famous detective. You even know this."

"And judging from the brake marks on the road, the red car seems to have no signs of slowing down at all, which further proves that this accident is such a phenomenon."

Hearing the discussion between Yuya and Michida Junko, Kurumiya Seiji raised his hands to cover his eyes and sobbed in pain: "There is such a phenomenon. Woo, if I had paid more attention to the side when I approached the intersection just now, such an accident would not have happened..."

Michida Junko glanced at him. Although she had seen many accidents as a traffic policeman, she still comforted the crying man out of habit.

But Yuya's idea was different from hers: "Whether there is such a phenomenon or not, according to traffic regulations, you should slow down or even stop to check at such an intersection, and make sure there are no vehicles or pedestrians before passing. Moreover, the red car on the right has the right of way. It is barely understandable that he did not slow down. Why didn't you slow down in advance?"

Michida Junko immediately changed to a scrutinizing look at Kuratani Seiji. As a traffic police officer, what she hates most is drivers who drive irregularly.

Kuratani Seiji was speechless and had to burst into tears: "I'm sorry, it's all my fault... woo woo woo..."

Yuya glanced at him and pointed at the surveillance screen and said: "I always feel that the red car's reaction is too slow. Even if it is really a collision route phenomenon that caused him not to notice the green car, but a car suddenly appeared in the blind spot, most people would subconsciously step on the brakes, right? But the red car did not have a similar reaction at all, and there was no trace of brakes on the ground..."

"Indeed..." Michida Junko looked at the screen and nodded thoughtfully.

The originally reasonable phenomenon, after being reminded by Yuya, she also felt it was unusual.

She suddenly realized something and looked at Yuya in surprise: "Kamiya-kun, is there another hidden story behind this car accident?"

Yuya neither confirmed nor denied, but glanced at Kurumaya Seiji with a calm expression.

Michida Junko felt that the matter was not simple, so she looked at Kurumaya Seiji: "Why did Mr. Kurumaya drive here?"

Kurumaya Seiji lowered his head and replied: "Nothing, I just happened to have time, so I thought of driving for a drive."

"Is it because the rainbow is beautiful?" Mao Lilan next to him suddenly spoke.

"Rainbow?" Kurumaya Seiji looked up at the sky in surprise, and found that there was no rainbow, and subconsciously asked, "Did a rainbow appear just now?"

Huh? Yuya's eyes flashed with a dark light, and he looked at Kurumaya Seiji with scrutiny, and Conan also looked at him with some surprise.

Sensing Yuya's gaze, Kamiya Seiji was a little nervous: "What's wrong, did I say anything strange?"

"No." Yuya shook his head, continued to watch the surveillance screen, and suddenly pressed the pause button.

Michida Junko subconsciously looked at Yuya: "What's wrong, did Kamiya find anything?"

Yuya looked at the surveillance screen with a thoughtful expression.

He turned his head to look at the deformed billboard, then walked to the side of the green car, looked inside for a few times, touched his chin and nodded.head.

"I see."

"Kamiya-kun?" Michida Junko followed closely behind Yuya, and her intuition told her that the detective seemed to have something to say.

Yuya glanced at her, returned to the surveillance camera, pointed to the screen and said: "Officer Michida, please pay attention here."

The place he pointed to was the glass of the red car in the picture, and it could be seen that it became brighter as if it was hit by light.

"What is this?" Michida Junko asked puzzledly.

Yuya explained: "The car glass suddenly became brighter. Considering the time and place, it should be the reflected sunlight."

"Sunlight?" Michida Junko touched her chin and thought for a while, and said with some doubt, "But, given the route of the red car, it shouldn't be reflected by sunlight? And at this angle, it looks like the sunlight is shining directly at it."

"That's right, because it's not the glass of the red car that reflects the sunlight, but that..." Yuya turned and pointed to the deformed billboard that was hit.

Michida Junko showed a look of realization: "So that's it, the billboard is indeed coated with reflective material to attract the attention of drivers. However, billboards are usually facing the direction of the road, so they won't have the effect of reflecting sunlight like that, right?"

Yuya smiled slightly: "What if the angle of the billboard has been adjusted by someone?"

"Adjusted by someone?" Michida Junko's face became serious, and she immediately ran over to check it out. As expected, in addition to the offset marks left by the green car, there were also scratches on the ground left by the reverse movement.

A large drop of cold sweat ran down Kurumiya Seiji's back.

Michida Junko ran back and said, "As Kamiya-kun said, the billboard has traces of being adjusted. Unfortunately, outside the range of the surveillance camera, there is no way to see who did it."

Yuya nodded: "In fact, if further testing is carried out, it can be found that the original direction of the billboard should not match the angle of the trace left by the collision with the green car. This can also be used as evidence that the billboard has been adjusted."

Michida Junko nodded seriously: "Okay, I will arrange someone to do the test afterwards."

"Then what?" She looked at Yuya expectantly.

Yuya continued: "After the billboard is adjusted, the light can be directed at the driver's eyes at a nearly straight angle. If it is normal, there is no problem with a short dazzle.

But for the deceased, he was already in the collision heading phenomenon, and was stimulated by such light. I am afraid that he didn't know what happened until he was hit by the green car.

This is why the red car didn't brake at all."

Michida Junko nodded repeatedly, thinking that Yuya's reasoning was very reasonable.

Kurumi Seiji's face looked a little ugly.

Yuuya suddenly looked at Kurumi Seiji: "What do you usually smoke?"

Kurumi Seiji subconsciously answered: "I don't smoke much..."

Yuuya tilted his head: "That's strange, your car is full of cigarette butts."

Kurumi Seiji's face suddenly changed.
