These automotive inventions that were once treated as a laughing stock have since turned out to be very impressive pieces of technology!

There are a lot of things in the world, when it just appeared, people do not recognize it, and even said it is a joke, reduced to people's after-dinner entertainment talk. But then it was realized that this thing is really powerful, and will even change people's lives. In the car is also the same, there are many designs in the beginning was treated as a laughing stock, and later found to be such a design is really great, and even changed the development path of the car. There have been countless milestone inventions in the development of automobiles in the course of their own development. At the beginning of each new technology being invented and applied, it is not accepted due to factors such as immaturity, high failure rate, and non-compliance with usage habits. But with the development of science and technology, the new technology is more and more mature, in the later application process, people will increasingly find the benefits of the new technology, and gradually from resistance to acceptance to love, and finally found that they can not leave it. Below we will talk about a few cars were once used as a laughing stock, and later found to be really powerful several inventions. In fact, the automobile has been treated as a laughing stock since the day it was born. At that time, the world was the world of horse-drawn carriages, the first car was invented, the noise is very high, the failure rate is very high, often break down on the road, not car pulling people, but people push the car, the world jokes, asserting that this is another "Fulton's stupidity", can not live for a few days. But with the development of society, now the horse-drawn carriages in addition to tourist attractions can be seen in other places are extinct, and the car really became the master of the world. 1, pneumatic tires: at the beginning of the invention of the car, the use of the wheels are wooden or iron, and later wrapped in a layer of rubber. The damping effect of such wheels was extremely poor, and the cars were very uncomfortable and could not travel fast. In the 1880s, John Dunlop made rubber hollow tires, and then Thomas made rubber hollow tires with valve switches, and pneumatic tires were born. However, due to the limited level of technology at that time, such tires are often flat, air leakage, and also not wear-resistant, so it is not accepted by the people, and even once reduced to a laughing stock. But with the advancement of technology and the tireless pursuit of automobile people, pneumatic tire technology is more and more perfect, and eventually became one of the greatest inventions on the car. It can be said that if there is no pneumatic tires, the car is unable to develop to this extent today. 2, front front drive structure: early cars, basically rear-wheel drive, which seems to have become the standard structure of cars. From the 1970s, a small number of passenger cars began to use the engine front, front-wheel drive structure. This was a groundbreaking initiative, which was highly criticized at the time, and even some automotive gurus directly suppressed it and trumpeted the shortcomings of front-wheel drive, which once made the development of front-mounted front-wheel drive difficult. However, with the development of society, people are more and more aware of the benefits of front-wheel drive, and more and more people accept, and gradually become the mainstream structure of passenger cars. Now more than 90% of the passenger cars on the market are front-drive structure, and even some of the luxury cars that regard themselves as rear-drive have begun to use the front-drive structure. This seems to fulfill the saying: practice is the only standard to test the truth! 3, collapse energy-absorbing body structure: I believe that until today, there are still a lot of people can not accept the "collapse energy absorption" this point of view. In the early and middle stages of the development of automobiles, people believe that the stronger the shell of the car, the car is the more secure, so people make the shell of the car hard and unparalleled. However, in actual automobile collisions, it was found that sometimes the damage to the car was not great, but the people in the car were injured, which ran counter to the fundamental purpose of automobile safety is to protect people. Until the 1960s and 1970s, automobile engineers began to study the collapsed energy absorption technology and applied it on cars. But such cars look very tragic in appearance when they actually collide, with badly damaged parts. Without looking at the people inside the car, people thought that the safety of such a car was even worse, and therefore they did not accept such a car as a joke. But with the development of automobile technology and culture, people increasingly realize that the essence of automobile safety is to protect people this point of view, the damage to the car is secondary. The collapsed energy-absorbing body structure does the best job in protecting the occupants of the car. Now the car is almost all this collapse energy-absorbing body structure, who say "the harder the body the safer" words, will be laughed at. 4, plastic bumpers: a friend of mine, until one day rear-ended a Mercedes-Benz, only to know that the car's bumper was originally made of plastic, and luxury car bumpers are also plastic! This is for him, is the existence of the destruction of three views. In his original concept, the car bumper should be steel, hard, so as to play the role of insurance. But the fact told him: the so-called bumper is a thin layer of plastic shell! He was depressed for a few days. In fact, the application of plastic bumpers in the 1980s began, is the collapse of the energy-absorbing body structure of the supporting products, the main purpose is to reduce the car on the pedestrian injury. But for a long time, people were unacceptable to this change, thinking that replacing steel bumpers with plastic ones was simplifying and reducing costs, which was detrimental to automobile safety. With the passage of time, automobile safety regulations more and more standardized, the advantages of plastic bumpers gradually highlighted, people eventually accepted the fact, and found that this change substantially reduces the pedestrian casualty rate, is very good indeed. In fact, the car in the development process, there are many similar technologies, such as electronically controlled engines, automatic transmissions, active suspension systems, differentials, etc., they can be said to be the invention that changed the history of automobile development. There are a lot of jokes that were once jokes, now become the truth, this is the power of science and technology, right?
