What if there is fog in the car?

The solution to fogging during driving is as follows: 1. Wipe with a wet towel: there is fog in the car when driving. You can find a suitable place to park and then wipe it with a wet towel. This method is practical, but it is dangerous. For example, there is fog on the highway, and the owner can't find a place to stop quickly. We can use other methods. 2. Window opening: Window opening makes the temperature inside the car the same as that outside the car, but this method also has certain limitations. This method is very useful in summer and can cool the car in winter. People in the car will feel particularly cold like this and can't use it in winter. 3. Turn on the air circulation system in the car: this system can play a role in ventilation. If you find fog on the front windshield of the car, you can turn on the pressurization system. You must turn on the external circulation system, so that you can achieve effective defogging. The disadvantage is that you can't drive for too long. The heating in the car will slowly disappear. 4. Turn on the automatic constant temperature air conditioner: it can quickly remove the fog inside the car and turn it on, without worrying about the low temperature inside the car, but the fuel consumption of the car using it will increase a lot accordingly.
