How Wide is the 30 Centimeters in Subject Two?
2 Answers
Subject Two's 30 centimeters refers to the distance between the right side of the vehicle and the right boundary line being 30cm. Dividing the Front Third of the Vehicle: Divide the vehicle into three equal parts. While driving, adjust the vehicle's position so that the front one-third of the vehicle aligns with the right boundary line. At this point, the distance between the right side of the vehicle and the boundary line is approximately 30cm. Observing the Windshield Wiper: Look at the windshield wiper and align its highest point with the boundary line while moving forward. Another method, though less commonly used but still effective, is to align the gap in the wiper with the boundary line while moving forward. At this point, the distance between the right side of the vehicle and the boundary line is approximately 30cm.
In Subject 2, that 30 centimeters is roughly the width of three smartphones put together. Driving instructors teach us to check the right rearview mirror—when there's just a finger's width gap between the car and the sideline, it's perfect. During practice, you can use a tape measure to get a feel for it; with enough repetition, your body will remember. During the test, maintaining this distance is crucial—exceeding it on the slope fixed-point stop will cost you points or even lead to failure. Think of the raised marks on the wipers: when they align with the road markings, it's about three fist-widths apart, making it much easier to remember. Essentially, 30 centimeters ensures enough turning space—too narrow and the rear wheels hit the line, too wide and the left side may cross. With daily practice in Subject 2, you'll gradually develop a feel for it without constantly fussing over the rearview mirror.
