How to judge the position of Jetta's right wheel? When starting on a half slope, it is always not placed within 30cm of the sideline of the right wheel position.

I'll teach you a way, whether the tire will hit an object (such as a point: a stone) on the road. First, the driver sits up straight with his head slightly to the right. When your eyes pass through the rotating root position of a wiper blade on the right and form a three-point line with the stone on the ground, keep moving in a straight line, and your tires will definitely run over the stone.

You can't see any wheels in the car. It is impossible to judge the wheel position without repeated mechanical exercises such as turning, turning and turning. This kind of judgment is difficult to express in words, and we can only rely on our countless practice to raise ourselves from perceptual knowledge to rational knowledge.

You aim at the position of the stone and then dozens of centimeters to the right is the position of 30cm. If the right front wheel is right in the middle of the stone, it is 30cm plus half the tire width.

A little experience, learn from you.
