See if you have seen these five cold knowledge about cars!

Recently, I have followed many car model reviews, but some friends said that Xiaomin’s articles are becoming more and more serious and they need to be checked.

Come on, then! come on!

Just kidding, kidding, making money is important, making money is important.

Today, Xiaomin brings you five related things that you must not have seencarOf cold knowledge. (If you read it, you pretend you haven't seen it!)

1. Dangerous racing cars without airbags

Racing as a high-risk sports event, the vehicle is not equippedairbagof.

Eat melon: Damn it! Isn't this cheating!

Xiaomin: Actually not, because the safety of the car does not require the tasteless configuration of airbags.

So what is the difference between a racing car and a family car?

First of all, the frames of the racing car are all strengthened by spot welding, and are installed with a roll cage, which greatly improves the rigidity of the car body.

The six-point type used on the carseat beltCompared with the three-point seat belt on a family car, it has better restraint, and when a collision occurs, it can well cushion the injury caused by inertia to personnel.

When a car race is in progress, the racers will be "fully armed". For example, a helmet can well alleviate the impact on the driver's head during an accident.

Therefore, airbags are not useful for racing cars, on the contrary they add extra weight.

2. It is said that the energy absorption of Japanese cars was first proposed by the Germans every day

This picture was popular all over the country at the time. As long as you talk about Japanese cars, there are many "patriotic" keyboard players on the Internet and they start to talk about theories such as thin iron skin and energy-absorbing XX.

The fact is that the first person who proposed the energy-absorbing design concept was a German: Bila Baenyi.he isBenzA proud engineer, later known as the father of automotive passive safety, he has more than 2,000 patents in his lifetime, which is twice the number of patents invented by Edison.

When a car collides, the impact force is dispersed by the anti-collision beam and the crush box.andbumperIn a collision, it can only serve as a buffer at most, so when you see the kind of bumpers on the Internet, it is basically "the planter is repairing the car"!

3. Many foreign brand models are only available in China

There are many car brands from foreign countries that will make certain models specially for China and sell them only in China. This is what we often call "special supply".

Xiaomin here roughly lists several common special models

Volkswagen Lavida (Interested friends can Baidu: Tokuhara Lang)

Honda Lingpai

BMW 1 series (sedan)

4. The birth of traffic lights was 18 years earlier than the birth of cars

In today's increasingly deteriorating traffic conditions, traffic lights have become an indispensable member of urban traffic. But did you know that the earliest traffic lights were 18 years before the birth of the car?

The first car in the world was born in 1886, but the signal light that can be used to sort out traffic, what we commonly call "traffic light", can be traced back to 1868, a full 18 years earlier than the car.

In September 1868, on the square of the Houses of Parliament in London, England, where there were frequent accidents of horse-drawn carriages hitting passersby, the mechanic Nayt installed the installation at the intersection of George Street and Bridge Street on the advice of the police governor Chad Maine. The first signal light in the world.

So the world's first traffic light was born.

5.Saudi Arabia once banned women from driving

It is an open secret that Saudi Arabia’s luxury cars are everywhere, but did you know that for a long period of time in the past, Saudi women were expressly prohibited by law from driving?

For a long, long period of time in the past, Saudi Arabia has been in the worldonlyIn a country where women are prohibited from driving, offenders will be fined or even jailed.

After the efforts of generations, finally in September 2017, King Salman of Saudi Arabia issued an order to allow women in the country to drive and have a legal driving license.
