Very interesting unpopular car knowledge, refresh your horizons!

1, the original purpose of high speed is the take-off and landing of aircraft.

We often see several highways attached to military airports on TV or on some nearby roads. They are different from our common ones because there are no obstacles around them, and some planes can even fly and land on the highways!

1at the beginning of 993, as soon as Hitler was appointed as German Chancellor, he went to attend the opening ceremony of the main Palin car and publicized the plan to start the expressway. During World War II, he ordered the construction of the first batch of expressways in the world, and personally set its standard for expressways: the average road is four lanes. The upper and lower floors are 34 meters wide, with a green belt of 5 meters in the middle; However, there is no street lamp, so it is required that the slope ratio of the road surface is small and the turning range can be large, because it is required to have a large radius, and the road surface is rough after special treatment, so that the tires will not slip when driving. However, his consideration of the expressway is not just for civilian use, but for war. The width of 34 meters is to adapt to the take-off and landing of fighters with a width of 30 meters. So after reading these, you will know why the highway can fly on it!

2. The consequences of not being used to using the handbrake.

Because there are more and more expressways now, urban pavements are basically made of cement, and the pavements are relatively stable, so many people are used to parking without holding the hand brake in real life. You know, this is more dangerous. However, hand brake is different from foot brake. You use steel cables to park your car. Both steel cables and iron have the same disadvantage, that is, they are easy to rust and corrode. If it is not used for a long time, it may lead to the disconnection of the steel umbrella and the hand brake. If you are caught in a traffic jam and just stop at a place with a slope, you should also find a stone to block under the tire to prevent the handbrake from slipping.

3. Come in the thunderstorm

Everyone knows that gasoline is a combustible gas. It is dangerous to refuel the car in thunderstorm weather, because when you refuel the car. Because lightning will conduct current to the ground. Ground objects are also charged, so it is easy for the refueling gun to introduce stray current into the gasoline and diesel tank. If you are accidentally struck by lightning, the consequences will be unimaginable. However, in general, gas stations are closed on thunderstorm days and will continue to be operated by some private companies. Attention, everyone. For safety reasons, it is best not to take risks.

4, the role of glass water

Automobile windshield water is a mixture of water, deionized water and various environmental cleaning agents, all of which are toxic liquids. This color can be clearly distinguished from other colors of liquids. But it is a consumable.

6. The North Pole doesn't lock the door to escape.

If you need to drive in the North Pole, you have to obey a law, that is, you can't lock the door. This is also puzzling. Why? In a place like the North Pole, cars are not afraid of being stolen, and they can't drive fast if they are stolen. There are no people or supplies for hundreds of miles in Fiona Fang, Fiona Fang, because most importantly, it is the territory of overlord bears, and there are many polar bears. The only way is to escape. If there is a car nearby or there is a car coming, it is safest to hide in the car, but you can't lock the door to leave an escape opportunity for those who run for their lives.
