What are the correct driving postures?

The correct position should be flush with the top of the head. Accurately speaking, the center of the headrest should be just opposite to the center of gravity of the driver's head, and the distance between the back of the head and the headrest should not exceed 10 cm.

When wearing a seat belt, the upper part should pass through the center of the left clavicle to ensure the best protection in the event of an impact. Now the vehicle can adjust the seat belt position, which is quite convenient.
