What does it mean to put your hand out while driving?

Hold out your hand when driving: avoid smoking in the car; I think this action is very handsome, pursuing inexplicable comfort.

1, avoid smoking in the car.

Cigarette smoke contains a lot of carbon monoxide. If there is poor ventilation in a closed car environment, it will cause the accumulation of carbon monoxide, and it will also work together with formaldehyde to increase the damage to health.

Smoking in the car is a very impolite and harmful behavior, especially for pregnant women and children. For various reasons, some car owners have developed the habit of sticking their hands out of the car.

2, the pursuit of inexplicable comfort

On the empty expressway, I reached out of the window and was slapped by a fan, which was very comfortable. If you are driving a luxury car, this action will make people feel cool.

When you put your hand out of the window, it is not only easy to be scratched by other vehicles, but also you may not be able to deal with it in time in case of emergency. So for whatever reason, I suggest you be cautious.
