How to judge the 30 cm distance on the right side during hill start?

[LeLeila]

There are mainly three methods to handle the 30 cm distance on the right side during hill start. Below are the detailed introductions of these three methods: Wiper method: For cars equipped with wipers, adjust your sitting position and observe the root of the wiper. When the point at the root of the wiper aligns with the extension of the right line, the distance between the right wheel and the side line is 30 cm. Reference object method: Use the central disk on the car hood as a reference. Draw a vertical tangent line five fingers wide from its right side, and align the leftmost edge of this five-finger width with the inner side of the white line. By driving in this manner, the right wheel will be within 30 cm of the side line. Rearview mirror method: Observe the small mirror on the car hood. When the side line touches the car body, the distance is correct.
