How to Judge 30 Centimeters?

[SanXavier]

After hearing the voice prompt, you need to drive forward and keep to the right. When you see the right front corner of the engine cover at the 1/3 position, the body is usually exactly 30 centimeters away from the roadside line. From the driver's seat, when the raised part of the wiper coincides with the right sideline, the distance should be approximately 30 centimeters. Observe the right front door handle in the right rearview mirror. If the right front door handle is tangent to the right sideline, the distance is just about 30 centimeters. If you have a good sense of the 30-centimeter distance, you can estimate it visually through the rearview mirror. Once the distance is confirmed, drive forward steadily with steady hands.
