How Wide is 30 Centimeters in the Rearview Mirror?

[OTalia]

30 centimeters in the rearview mirror is approximately the width of two fingers. When determining the 30-centimeter distance in the rearview mirror during a driving test, here are some useful techniques: Observe the wiper protrusion: From the driver's seat, when the wiper protrusion aligns with the right-side line, the distance is approximately 30 centimeters. Check the right front door handle: Look at the right front door handle in the right rearview mirror. If the handle is tangent to the right-side line, the distance is correct. If it's too far, adjust the direction slightly. If it's too close, there's a risk of crossing the line. Look at the one-third point of the car's front: When the right one-third point of the car's front aligns with the right-side line, the distance is exactly 30 centimeters. It might be challenging to locate this one-third point consistently, so it's helpful to mark it during practice and remove the mark once you're accustomed to it.
