On the road.
At this time, it is the rush hour, the traffic is crowded, the speed is very slow, and the congestion can be seen in the corners and corners of the city, whether it is a relatively narrow branch road, or a very wide trunk road, but it is difficult to avoid.
Even, on some fast lanes, you can see the phenomenon of "ghost traffic jams".
"This ghost traffic jam phenomenon, to put it bluntly, there is no accident, no vehicle stoppage, and no closed construction lane, but it is inexplicably blocked, and the congestion lasts for a long time, but the phenomenon of driving without warning becomes unblocked, in fact, it is quite common."
Chai Hua said: "There are quite a few reasons for this phenomenon, it may just be that a driver suddenly slows down or changes lanes to overtake, which triggers a series of chain reactions in the rear car, and eventually causes congestion." ” "You think, our human nerve reaction speed is limited, it takes a certain amount of time, roughly two hundred milliseconds, that is, about 0.2 seconds.
Don't look at this time is very short, but add the reaction time of the car, decelerate and then accelerate, and this time will be long. ” "Maybe one car or two cars, it's still not so obvious, but once there are more cars, twenty or thirty or even hundreds, the time is superimposed, it is considerable, and eventually causes congestion."
"Cauliflower," Yuan Youchong interrupted him and said, "I understand this truth, you don't have to deliberately popularize science with me." ” "Uh" Chai Hua smiled bitterly and said, "It's not like there's nothing to talk about, it's rushing to get off work, take a fast track, and I ran into a ghost traffic jam, which is very annoying." ” "Well, traffic jams are a real test of patience."
Yuan You shook his head, and then said: "Then again, how can you be sure that this is a ghost traffic jam, not some accident?"
"Intuition," Chai Hua said: "Our Huayang, like you Xin'an, has a huge population density, and you can often encounter ghost traffic jams when commuting to work, and we have somewhat summed up some experience." ” "To put it simply, although they are all stop-and-go, the traffic jam caused by the accident is generally much more serious than the ghost traffic jam, and the pause time is longer, and you see now, my foot has been stepping on the clutch, stepping on the sour.
Hey, a manual transmission car is not good at this, tiring. ” Yuan You shook his head, then glanced back and said, "Have you noticed that the car behind has been following us for a long time." ” "Hmm" Chai Hua glanced at the rearview mirror, shook his head and said, "I didn't pay attention."
However, he can't overtake the traffic jam, and there are not many entrances and exits on the expressway, what's strange" "I always feel that something is not right."
Yuan Youchong shook his head and said: "You think, we are driving a police car, and we can't change lanes at will, let alone add traffic jams indiscriminately, so occasionally when the side lane is relatively smooth, we can only watch and walk this road with peace of mind." ” "But the car behind is different, I noticed that the car in the back, and then the one behind, basically changed lanes and even forcibly turned around when the surrounding lanes were relatively smooth, and the car behind them followed us persistently."
"Moreover, when our road was relatively smooth, you see now, he is biting very hard, for fear that others will add a plug, if there is really a car trying to squeeze in, I guess he will hit it directly."
"Maybe the quality of other drivers is relatively high," Chai Hua still didn't care too much, and said: "Or maybe the road experience is not too rich, and I don't dare to plug in the past."
As for the tightness, it's easy to understand, he doesn't forcibly change lanes himself, it doesn't mean that he is willing to let others add plugs. ” "What about the car in front" Yuan Youchong pointed forward again and said: "He just came in, himself, squeezed into front of the police car, I couldn't help but want to give a thumbs up, and it also proved his skills and courage, and there is no need to say more about the quality or anything." ” "But since it squeezed in front of us, it hasn't changed lanes, and it has become a good citizen at once, you say it's strange."
"Hey, you really mean that when you say that, it's kind of funny."
When Chai Hua heard this, he also frowned, but he was still a little unimpressed: "But, what do they want to do, follow us, and then dare to do anything wrong to us."
"I don't know," Yuan Youchong frowned and said, "But let's be careful."
If it's just a coincidence, but if they really have the intention to follow and have evil intentions, the only one with this motive and courage is the criminal group we are tracking. ” "Yes" Chai Hua was excited, and immediately became serious, and no longer regained his relaxed and unimpressed appearance.
If they're really members of a criminal syndicate, that's deadly.
If you're not afraid of 10,000, you're afraid of what happens, it's better to be careful, after all, a dog's life matters.
However, the traffic jam was quite tiring, and it was a torture to concentrate on the vigilance, and it didn't take long for him to sweat on his forehead.
What's even more painful is that even he can't tell what he is guarding against, only to keep a distance from the front and rear cars and take precautions.
Finally, after another ten minutes or so, the lane suddenly became very normal without warning, and he realized that he had driven out of the range of "ghost traffic jam".
But instead of relaxing, he became more nervous.
If the two cars in front and behind really have bad intentions, then at this moment, it is possible to do it.
Thinking of this, he glanced in the rearview mirror from time to time, looking for an opportunity to try to change lanes and get rid of the front and rear cars.
However, the drivers of the other lanes seem to be eager to vent their grievances after experiencing traffic jams, and they are driving fast one by one, basically touching the speed limit line.
In addition, the density of vehicles is still relatively large, so he can't find a chance to change lanes.
Moreover, the speed inevitably rises slowly, after all, the road is not driven by his house, and it is impossible for him to be allowed to drive gracefully on the expressway.
What's more, he is not occupying the slow lane now.
There was no way, so he had to keep an eye on the two cars in front and behind to prevent accidents.
Just as they were speeding at 70 mph, the car in front of them suddenly braked suddenly.
Seeing this, Chai Hua, who had been on guard for a long time, also hurriedly stepped on the brakes, but fortunately, the distance between him and the car in front of him, although it was not much in the case of the deliberate suppression of the car in front, it was not small, and it should be able to brake.
But before this thought was finished, he and Yuan Youchong suddenly felt an obvious and huge feeling of pushing back, and then they saw that the distance between themselves and the car in front was getting closer and closer "Damn, the car pressed the accelerator" he scolded in his heart, while holding the steering wheel hard to prevent the direction from deviating under the impact and causing a bigger tragedy, and at the same time no longer hesitated, and pressed the brake with his right foot to the end.
Finally, there was another loud bang, and the police car and the car in front also collided with the torture and murder :
