How to Find 30 Centimeters Without Looking at the Wiper?

Align the one-third point of the car's front with the right-side line and proceed forward. Divide the car into three equal parts; if you can't find this point initially, you can make a mark yourself. Another commonly used method is to align the right-side reinforcement bar with the side line and proceed forward. Parallel parking is one of the items in the driving test's Subject 2.
I've been driving for over 20 years and can maintain a 30 cm distance without looking at the wipers—the key is practicing to develop that feel. Every time I park or drive slowly, I make it a habit to glance at the roadside line; aligning the car body with it ensures accuracy. You can also use the reflection of the roadside in the rearview mirror as a reference—memorize that angle, and the car won’t get too close to scrape. When practicing, choose an open road and try it repeatedly a few times to find the rhythm. Over time, your body will remember the position naturally, just like riding a bike. This method has helped me drive safely in all kinds of weather, especially useful in rainy conditions with poor visibility. Once it becomes a habit, your driving will be steadier and more confident.
I think the most reliable way to find 30 cm is by using fixed points inside the car, such as adjusting the seat position and resting your head against the headrest, then focusing on the intersection of the windshield's lower edge and the ground, or aligning the driver's door handle with the roadside parallel line. Experiment with different distances and seat adjustments—SUVs, being taller, make it easier to judge, while smaller cars may require fine-tuning your perspective. Practicing slowly while reversing or parking by the curb helps build experience—don’t rush for instant mastery. Once familiar with these reference points, combine them with your driving posture to achieve safe and efficient parking. Now, I apply this method to any car I drive, making it hassle-free and reducing the risk of scrapes.
