The Simplest Method to Find 30 Centimeters
3 Answers
The simplest method is to divide the front of the car into three equal parts. When the right one-third of the front aligns with the sideline, the distance between the car body and the sideline is exactly 30cm. During the operation, continuously observe from the rearview mirror. When the reference point coincides with the sideline, immediately press the clutch and brake to stop. The skills for pulling over are as follows: 1. Turn on the light: When hearing the voice prompt "Please pull over ahead," first turn on the right turn signal. 2. Position: Pay attention to observe the right front and find a suitable parking spot. 3. Slow down: It is recommended to slow down to below 10km/h, shift to first gear, and the slower the speed, the more beneficial it is for the next operation.
Maintaining a steady speed of 30 km/h while driving is quite simple for me. The first trick is to keep an eye on the speedometer display. Many cars nowadays come with digital or analog speedometers, so I just watch the number jump to 30 and that's it. This speed is commonly used in the city, where speeding can easily result in fines from speed cameras, so I'm accustomed to using the cruise control button to set it with one click—convenient and worry-free. The car's speedometer can occasionally have slight inaccuracies, so I use my phone to open a navigation app like Gaode Maps, which displays real-time speed for comparison to ensure accuracy. During regular maintenance, I also ask the mechanic to check the speed sensor to prevent malfunctions, making driving much safer and more reliable. While driving, I maintain a relaxed mindset, avoiding constant throttle adjustments to prevent speed fluctuations—keeping a steady pace is the smoothest way to go.
As an experienced driver, I rely on my experience and intuition to reach a speed of 30 km/h. On familiar routes, I listen to the engine sound to gauge the RPM, usually just gently pressing the accelerator at idle speed to maintain it. You can also reference roadside objects like trees or streetlights to pass by at a steady speed. However, beginners might not be as accurate, so it's advisable to rely on the speedometer, as most cars are responsive at low speeds. Mobile GPS can also help calibrate speed to avoid speeding tickets from traffic cameras. Safety comes first—be cautious in urban speed-limited zones. Developing a habit of frequently checking the dashboard is beginner-friendly, simple, and efficient. Remember, maintaining a steady speed saves fuel and reduces wear.
