First of all, it is necessary to check the vehicles before going out. It is better to invite several more cars to go along the same road and take care of each other when taking a self-driving tour.
Second, timely understanding of road information, before driving, we must grasp the road information in advance.
Thirdly, driving at a uniform speed. In winter, driving at a uniform speed should be avoided. In order to avoid accidents such as rear-end collision, we should try our best to keep the vehicle moving at a uniform speed, especially on ice and snow roads.
Finally, we need to be prepared for "occasional needs". We need to know that when we go out, we need to be considerate and take into account all the problems we may encounter on the road as much as possible in order to prepare for occasional needs.
