Historically, there have been many pseudo-science issues concerning the use of cars, and some of them appear to be reasonable but just imaginary. The following are just some of the arguments. Do you believe it?

Confusion 1: Frequent line changes can increase speed

From the left lane to the right lane, and from the right lane back to the left lane, which lane is faster and which lane is going to go, this is something that many Chinese owners often do, sometimes even "subconscious" because it becomes too much Make it a habit.

Can frequent lines change speed? The answer is yes, but it is minimal.

Some media have done tests, 50 kilometers of city roads, rush hour, two cars at the same time, a frequent change line, one is following the traffic, without speeding without emergency lanes, both before and after Just two minutes difference. This two-minute lead was achieved with the danger of scraping, rear-end collision, whistle warning and other warnings. It is not difficult to determine whether it is worth it.

Confusion 2: The car door to reduce the temperature

There was a video on the Internet that was very interesting. A Japanese car owner repeatedly turned the car door and pushed the air outside the car into the car to lower the temperature inside the car, so as to achieve the purpose of delaying the opening of the air conditioner or not opening the air conditioner, thereby reducing fuel consumption.

This practice is established. Repeatedly knocking down the door, the temperature inside the car will be much lower than when the car was just opened, and it is roughly the same as the outside temperature. However, the corresponding price is to cause extra damage to the door-related structure. We must know that every spare part of the car has a service life.

Confused three: follow the car can save fuel consumption

A large part of the energy of objects in motion is used to resist wind resistance. Therefore, in long-distance running, people who follow and run will be much more relaxed, whether the car is the same, and whether the fuel consumption is lower than others?

The answer is yes, but the premise is that the distance between the two cars on the highway cannot be too long. The “not too long” mentioned here can be shorter than the regulations. If the effect of fuel saving is good, the distance between the two cars should be within 50 meters or even shorter. A distance of 50 meters means that the front car will brake slightly and you will bump into it. It seems that it is not very cost-effective to trade about 20% of the fuel-saving effect at the risk of such a huge rear-end collision.

Confusion 4: After one or two o'clock in the morning, it is not sleepy

The people who have stayed overnight have such experience. After one or two o'clock in the morning, that is, “the point of going through sleep”, people are refreshed and not sleepy. Working at home or so is not suitable for driving. Three to five in the morning is the high accident period. The reason is not the other one.

A number of long-distance drivers said that there was indeed a sober period at one or two o'clock in the morning, but it was very short, only about one hour. However, it was followed by more intense drowsiness, boring straight roads and passing across from time to time. The high-beam lights... will unknowingly “hypnotic” the driver, “sometimes, falling asleep without knowing it”. Is it useful to drink tea and coffee? It is useful for the first two times, but it is too much to drink. The most effective way is to change people or stop to sleep.

Confusion 5: Use the car window when flooding

How do you escape when flooding or a car falls? This question must be known. Theoretically, when the water fills the car, there is a short time to open the doors and windows to escape. However, not everyone is so calm, and no one can guarantee that the doors and windows are still in good condition. What should I do if I die?

Someone thought of using their ankles to smash their windows. This statement is also risky, because the windows are not necessarily open enough, their sturdiness, beyond imagination, not leather shoes can do anything. The best way is to put a special hammer on the glass in the car, and can not be placed in the boot, in the glove box in the passenger seat, a key moment, a hammer to get.

Puzzle six: take a taxi cheaper than buying a car

This statement has a long history. Every once in a while, related discussions or bickering will appear in major auto forums. Those who support taxis think that although the unit price is high, there are no problems such as fuel costs, parking, insurance, and maintenance. It is not necessary to spend a lot of money on vehicles. Investing with the money of a car can even earn the cost of a taxi.

For this argument, the correct conclusion is: The single measure of expenditure is established, that is, taxi is always cheaper than buying a car. However, if other factors are measured, such as convenience and dignity, the cost of buying more cars is worth the money.

Looking at a problem depends on which angle you are standing in. The majority of those who support taxis are those who have not bought a car. However, one day, they become owners and it is estimated that there will be other opinions. The key to taking a taxi or buying a car is economic affordability and family needs. You need to buy it, and you don't need to buy it.

Confusion 7: 97 oil consumption is even lower

Over the years, with the popularity of oil No. 97, the saying “one dollar, one goods” has been heard from time to time, and many owners have begun to tangled up. "The oil will add a little better, the car will be more powerful, the fuel consumption will be lower," and "No. 97 has more protection for engine protection. In the future, the price of car dealers will be higher."

This argument is not valid. The gasoline with different markings in China is not divided into multiple fractions. Instead, after different “one shot” moldings, different doses of antiknock agents are added to gasoline to meet different anti-explosion standards.

In other words, the "base" of No. 93 oil and No. 97 oil is the same, but it is only the difference of additives. Therefore, what gasoline is added depends on the requirements of the vehicle. If 93 can be added, there is absolutely no need to add 97, and spending more money will not damage the engine. The No. 97 oil is no better than No. 93.
