Hello, Mr. Ma Hao, Zhangqiu Calligraphy Training, to answer your question: It is suggested that the most important thing is to control the speed when walking in the S-bend, and keep the same speed when doing every movement, so as not to slow down for a while. This is very important. When entering the S-bend, pay attention to the position of the front of the car and try to drive in the middle. Pay attention to your speed when you are ready to enter. Not too fast. It is best to keep a constant speed and enter at a low speed. When the left corner touches the right line, make a 45-degree circle to the left to keep the left corner at a certain angle with the line on the ground. Take the first turn on the right line of S Road, and the car won't press the line and get out. When you slowly finish the right line of the first corner, the direction will not move. When the left corner of the car touches the left line of the second corner, it will return to the positive direction and circle 45 degrees. Let the car walk slowly for a while at this time. When your right corner intersects with the left line of the second bend, draw a circle of 45 degrees to the right. At this time, the right bend and the second bend are at a certain angle, so the car will not press the line and will not bend. Finally, I wish you drive your own BMW all the way, and you can get full marks in every project.
