Hold the steering wheel when you see the left front corner of the car pressing inward along the right outer edge line of the S-bend, and then look down from the left front corner of the car. When the left front corner of the car rides to the left edge line of the S-bend, turn the steering wheel to the right and move on. At this time, look down from the right front corner of the car. When the right front corner of the car rides 30 cm on the left edge line of the S-bend, turn the steering wheel to the right, and then watch the right front corner of the car slowly turn the steering wheel to the right to make the right front corner of the car.
When the right front corner of the car leaves the S-bend, hold the steering wheel and keep moving until the front wheel of the car leaves the S-bend, and turn to the left to drive out of the S-bend (in fact, it is better to let the car come out slightly obliquely along the center line of the S-bend)!
These are the driving skills in curve driving. Be sure to practice driving more, and you will understand after a few more practices. Think more when practicing. Don't just practice, think more, it's easy to find the law.
