In fact, most people are similar to Wang Jingze, especially when eating.
Before the popularity of this and mobile payment, I was always worried about insecurity, bad use, and I couldn't stop using it.
Some configurations look unreasonable, strange and strange, after really using, the configuration that cannot be separated from the 180 ° turn is also there.
360° panoramic imagery
Why some drivers feel that they don't need 360° panoramic images
The first is the 360° panorama.
I have a good end of this mirror, a good end can probe to see, and this thing is expensive, the so-called "high-tech" is not more than 2 cameras? The road and door are all there, what is the use?
And you see, I looked in the rearview mirror, one hand on the steering wheel and one hand to the side, didn't I? "Oh" fell over, this is called "old driver", how handsome? It's easier to have a girlfriend, isn't it?
How the 360° panoramic image is really fragrant again
How to say this thing, in fact, a large part of the real old drivers are still inclined to accept the auxiliary configuration of 360 ° panoramic images.
I like it myself, so people are very strange to see how when I reverse the car, how to always look down at the screen, not look at the mirror.
Lu Nengchao et al. published a paper on "Transportation System Engineering and Information", "Research on the Effect of Driving Experience on Advanced Driver Assistance Systems", as mentioned above.
The acceptance of advanced driver assistance systems by skilled drivers is significantly higher than that of unskilled drivers.
Because the old driver understands, even if they have been hit, even if there are rearview mirrors, there are still many blind spots on the side of the car that cannot be seen, and 360 ° panorama can solve the problem of blind spots.
Zeng Junyan of Chongqing Jiaotong University has a master's thesis, "Research on testing and evaluation methods of automobile blind area monitoring system", which said above.
The driver's field of vision is obscured by the body pillars and windows, there is a blind spot of about 60 degrees, and more than 80% of the information in the driving process is basically obtained by the eyes and vision.
To put it simply: the blind area around the body is very large, and after installing a 360 ° panoramic view, the amount of information that can be obtained by relying on vision is completely different.
It's like: You go play a glory of the king, today it said a very powerful auxiliary software, you spent a lot of money to buy, hiding in the grass that the person you can see what he is doing, it's different, right?
In addition to observing the blind spot, some 360 ° panorama also has a video function, in case of encountering a small accident on the side or touching the porcelain, this kind of does not have to be ripped off, and the last time it is used to return to the original.
Plastic bumper
Why do people think plastic bumpers are cutting corners
What is the second one called? Plastic bumpers, this is the local language, some called "resin", are professional materials, not necessarily plastic.
This is like a paragraph, there is no wife in the wife cake, there is no bar in the bumper, and it is not safe, right? Made of plastic, it looks like this is really unreliable, this phone case level thing, right?
There are also many such accidents on the Internet, the car hit, the bumper directly cracked; hit a dog, the dog is fine, the bumper fell down; a chicken rushed into a bumper; the front of the bicycle was inserted into the bumper...
A lot of people say that this is still cutting corners, but it just can't work, isn't it?
In fact, plastic and plastic are not the same
In fact, the plastic we recognize is really different from the plastic it uses.
Daily packaging boxes, beverage bottles, basically the scientific name is called "polyethylene (PE)", "polypropylene (PP)", "polyterrhealic acid (PET)" plastic, anyway, P began.
The plastic parts on the car are mostly PP modified materials, which are pro versions, plastic Pro, plastic Plus, and the performance is much stronger than ordinary plastics.
There may be a lot more of these plastic pieces on cars than you think they exist.
Liu Zhuang published a paper in "Times Auto", "Automotive Exterior Plastic Parts Coating and Coating Quality Evaluation Analysis".
Above: At this stage, the use of plastic parts in a car has reached about 200kg.
This is because plastic can reduce weight, can reduce some fuel consumption. In addition, when used on the bumper, you don't have to worry about rusting off the paint.
Simply put: unless it is painful or ugly, it will not rust or break when placed there, no matter what, the maintenance cost is low, right?
It's really good to use
In addition to good durability, the reason why "plastic bumper" was chosen is because the collision resistance is better.
"Ahhhhhhhhhhhhhhhhhhhhhhhhhh How good the steel bars are. It wasn't until he rear-ended a Mercedes and got out of the car that there was no trace of it, only to find that the plastic bumper also had a fragrant part.
When there is a slight collision, the plastic can play a certain cushioning role.
It's like: an egg falls to the ground and "clicks" isn't it? It broke open and shattered. Can the ping-pong ball still bounce when it falls to the ground? That's the feeling, right?
Even if you hit a pedestrian, the likelihood of injury is relatively low.
Jiang Xuehao published a paper on "Internal Combustion Engines and Accessories", "Discussion on the Properties of Commonly Used Materials for Auto Bumpers", which was said above.
In order to reduce the damage of the car to the human leg in the event of a sudden situation, it is necessary to control the deformation amount of the bumper when it is hit between 50 and 75mm. If you use a metal bumper, the amount of deformation cannot meet the requirements.
The man who hit "Oh Yo Yo" immediately got up: "You bastard, how do you drive?" "Looks like a fierce scolding, right?"
If the metal bumper "clicks" and he lies on the ground without saying anything, and the reaction is gone, are you afraid or not? In fact, it is such a thing, he does not scold you, the reaction is gone.
Daytime running lights
Why do people think that daytime running lights are a laughing stock
The third is the daily running lamp that we have been talking about.
I have talked about "Daytime Running Lights are NOT IQ Tax" in the video before, this time simply said, the reason why I think this daytime running lights are useless, mainly because this thing does not affect the car experience much.
The daytime lights were turned on, and others could see it, but I couldn't. Even if I don't open it, it seems that there is no significant change, and no one has ever driven to the side of my car and said, "Friend, your daily lights are not turned on, turn it on." "Isn't it?
If we meet a well-meaning person, at most we can say, "You don't have a lid on the fuel tank. "Sometimes it's said on the road, right?" The daytime lights were not on, and no one had ever talked about it.
It's a flashlight in the daytime, this solar flashlight, isn't that a waste of electricity, is it?
Moreover, at present, there is no mandatory use of daily running lights in China, and whether it can be opened or not is also with everyone.
It's actually quite useful
However, the European Union has regulations, we may wish to take a look: all new cars, all kinds of new trucks and buses must be equipped with day running lights.
According to the Dutch Ministry of Transport, driving with the headlights on during the day reduces the chance of serious traffic accidents by 5% to 12%. So it's really useful from the actual statistics, although we don't feel anything.
The role of the daytime lamp is the same as the roof of the building, you see the tall kind of building, "zhuazhua" flashing a small red light, what is this thing for?
Is it for good looks? If it looks good, why are all the buildings with bright red lights and no colorful lights?
The scientific name is "Aviation Obstacle Light", which is to prevent the plane from accidentally hitting this thing, and our daily running lights have a similar warning effect.
Another is that we encounter smog days, rain and snow days, and we may feel that we have a good line of sight.
But in fact, the opposite car, the car behind the side, turned on the daytime lights and did not open, he noticed that the ability of our own car or the visibility difference is still quite large, their safety is not our safety, right?
These 3 are practical configurations
So, in general, 360° panoramic images, plastic bumpers, and daytime running lights are actually practical configurations.
The reason why it is used as a joke in everyone's chat is that on the one hand, it is entertainment and happiness, on the other hand, it is possible to recognize the above, and everyone's differences also exist.
Which 4 configurations look good, it is really a laughing stock
Just now those are after dinner to talk about, those things sent by the online GIF, the configuration is more critical or practical, right?
Which configurations are recommended, practical, and do not support post-installation? Which accessories are quite practical, do not buy them in 4S stores, and install them yourself cheaper and better? Which accessories should we not install?
A total of 8 dry goods, materials, are sorted out for everyone, want to see is very simple.
Keyword: configuration
Pay attention to the WeChat public account "spare tire car", reply to the keyword "configuration" can be.
I this public number, every day will give you a piece of car practical small dry goods, text, audio, video have, pick your favorite can be, "spare tire said car" waiting for you to play Oh.
