Why do old drivers repeatedly warn: in the no-man's land of Tibet, do not live in the car at night?

Friends who go to Tibetan areas for self-driving tours will definitely receive the advice of the old driver, and when spending the night in no man's land, do not stay overnight in the car, but when you ask again and again, the old driver smiles deeply and tells with the tune of the person who came over

"Listen, don't ask why!"

No man's land overnight, really can not stay overnight in the car?

What's different about no man's land? In fact, there are really beasts, such as beasts: Tibetan wolves in Tibetan areas are one of them, this and Mongolian wolves are actually a species, although the size is not particularly large, but ordinary people are by no means the opponents of Tibetan wolves, and there is the largest wolf pack in China in Tibetan areas, the total number is similar to that of other provinces and cities in China!

In addition to the Tibetan wolf, there are Tibetan brown bears, of course, this is more terrible than the wolf, to say that the vitality of encountering wolves is still quite large, but if you encounter brown bears, it will be less fierce, and wild yaks also have to be careful, that thing is very powerful, can overturn the car!

So you'll encounter beasts in the overnight car? However, the bear can slap the car window with one slap, but the wolf seems not to be able to, after all, the car glass can still block the attack of the general wolf, unless the assistant runner hits the window with the wolf's head!

Therefore, the car can still protect people, why can't it be in the car? It's better than being out there, isn't it? However, even outside the accommodation point in Tibetan areas, it is not recommended to stay in the overnight car, although there are almost no wolves and bears here, but the danger inside the overnight car is not beasts, but lack of oxygen!

We know that Tibet is basically on the plateau, the average altitude is almost 4000 meters, at this altitude, the total amount of oxygen in the air is less than 2/3 of the plain, many people will have altitude sickness when they are above 2500 meters, and most people will experience altitude sickness when they are above 3500 meters!

Altitude sickness is the human body in the high altitude state due to the reduction of oxygen concentration in the blood and the appearance of acute pathological changes, at this time once the cold may cause alpine pulmonary edema or cerebral edema, this course of development is very fast, very dangerous, so there is still a certain risk to go to the plateau!

Isn't everything the same inside and outside the car, and why is there a lack of oxygen in the car?

This is mainly related to the operation, the plateau day and night temperature difference is extremely large, the car is basically not insulated, so the car is very cold, at this time if you open the window then the cold wind will drill in, it is easy to raise the glass window, and at this time the air inside and outside the car is difficult to circulate, so it is likely that an unexpected suffocation accident will occur!

Friends who have self-driving trips in Tibetan areas say that they have the experience of spending the night in the car, cold is the deepest memory, several times can't help but close the window, but reason tells him no, must not close the window! The other is uncomfortable, sleeping in the car can not show their fists and feet, sleep sore, it is too uncomfortable!

This is the main reason why it is not recommended to stay overnight in the car, of course, if it is a caravan, it is another matter, it is specially designed with a thick insulation layer, the glass is generally double-layered, there is also a corresponding ventilation system inside and outside the car, and the space is relatively large, even if it is not breathable, the air in the car can also ensure a long time of breathing, in such a place overnight, undoubtedly much safer than the ordinary car!

When you do not carry the camping equipment outside the car, there are beasts around the threat, if you know what the consequences of sleeping in the car, then please put a thick towel or other objects on the window when you rest in the car, so that the window cannot be closed, there will be a slit, to prevent you from sleeping until you are confused and unconsciously close the window!

Extended reading: Why should old drivers in Tibetan areas bring portable oxygen tanks?

Are diesel cars or gasoline cars good in Tibetan areas? Many friends think that diesel vehicles are better, after all, diesel vehicles have low speed, large torque, and the probability of getting out of trouble in Tibetan areas is relatively high, while gasoline vehicles do not have these advantages, so go to Tibetan areas to choose diesel vehicles!

In fact, it is really wrong, because the general Zero diesel antifreeze -4 ° C, basically can be used around 4 ° C -8 ° C, in Tibetan areas to add -35 diesel, its antifreeze range is -14 ° C -29 ° C, but in Tibetan areas may not be added -35, then it is a break, because the Tibetan area has a plateau at night is very cold, if the Zero diesel on the plateau, it is estimated that it will be finished, you have to wait until the oil road freezes before you can get off!

When there will be a bed quilt and portable oxygen tank, the former is used to keep the car warm at night, the latter is to spray oxygen on the air intake when landing, making the car easier, generally two-pronged, once on the car!

So if you go to Tibetan areas by car, then it is recommended to use a gasoline car, because gasoline antifreeze is very good, the general freezing point is -75 ° C, almost the temperature of dry ice sublimation is slightly higher, relative to the lack of oxygen, gasoline cars are easier to get on!
