When Your Car Sways at High-Speed Corners, Master It with Out-In-Out Cornering — Practical Techniques from Yoon Chul-soo Driving Academy

This article covers lane-changing and high-speed driving techniques established by YCS Motorsports Group CEO Yoon Chul-soo and President Shim Jae-woo, based on approximately 40 years of racing circuit experience. This principle is not only applicable on racing circuits but also on everyday roads and is the core habit that dramatically increases driving confidence. Through a correct understanding of cornering—the starting point for escaping beginner driver status—let's learn how to control your vehicle stably in tense real-world driving situations.

Out-In-Out cornering is a simple yet powerful principle. When entering a corner, you start from the outside (Out) of the lane, pass through the inside (In) of the corner, and exit again to the outside (Out), creating a specific path. This is not merely "drawing a pretty line," but a physics-based driving principle that controls the vehicle stably within the grip range of the tires.

The core principle emphasized by CEO Yoon Chul-soo is "driving is about control, not speed." Understanding this principle allows you to predict and precisely manipulate your vehicle's movements when changing lanes on a highway, turning at a tollgate exit, or encountering unexpected rotations on wet roads.

* Designing a stable path that maximizes tire grip
* A technique that clearly separates the order of braking, steering, and acceleration
* Preventing skidding through understanding the vehicle's weight transfer principle

Most of the tension beginner drivers feel when entering a highway stems from lane changes. This is because drivers hastily turn the steering wheel without a precise entry path. According to Yoon Chul-soo Driving Academy's correct driving position principle, the "entrance" position of the corner must be determined before the lane change.

When your vehicle starts from the outermost position before entering a corner, you have room to turn the steering wheel slowly. This is precisely why the "Out" point is so important. Conversely, if you start a lane change too late, sharp steering becomes unavoidable, and at that moment, your tires squeal and skidding occurs. The anxiety of that moment makes subsequent driving even more inhibited.

* A visual technique of drawing the line with your eyes starting 50m before lane change
* Training in predictive ability by calculating corner entry speed in advance
* Securing precision by adjusting both steering wheel manipulation width and speed simultaneously

The Out-In-Out technique taught at Yoon Chul-soo Driving Academy consists of the following five steps:

Driving safely on regular roads and driving quickly on a racing circuit ultimately rely on the same principle. The difference is not in speed but in consistency. The proper driving posture emphasized by CEO Yoon Chul-soo stems from three key elements.

First, postural control. From the moment you sit in the driver's seat, your backrest should be in a straight line, and your elbows should be at 90 degrees when gripping the steering wheel. Precise steering is only possible from this position.

Second, breathing consistency. When you're tense, you hold your breath, which leads to muscle stiffness and dulls your manipulation. Breathing at a steady rhythm while driving allows your body to relax and your reactions to speed up.

Third, gaze management. Many beginner drivers only look at the road directly ahead of their car. However, experienced drivers "read the curve in the direction of travel." This difference determines your confidence in changing lanes on highways.

* Maintaining high concentration while keeping your body relaxed — seemingly contradictory but the condition for peak performance
* Sensing your vehicle's movements through sound — judging the current state by tire sounds and engine noise
* Balancing prediction and responsibility — anticipate the next situation but adjust your final decision to the current circumstances

At Yoon Chul-soo Driving Academy under YCS Motorsports Group, beginner drivers who want to graduate from beginner status receive one-on-one lessons every month. Let's examine one case.

Mr. A was a driver three months after obtaining his license who had never driven on a highway. From the moment he entered the highway after passing through a tollgate, his hands became sweaty, and when faced with lane-changing situations, he trembled so much he could barely control the steering wheel. In the first session, Supervisor Yoon Chul-soo diagnosed Mr. A's biggest problem: "Your gaze is fixed 5 meters directly ahead, and whenever you try to change lanes, you suddenly become afraid and give up."

The supervisor applied the Out-In-Out principle and taught him to prepare for lane changes starting 50m in advance. Specifically, he repeated four-stage training: (1) securing the outer lane position from 100m before, (2) looking 30m ahead in the direction of travel from 50m before, (3) turning the steering wheel slowly, and (4) returning to straight-line driving with ease after passing through.

Four weeks later, Mr. A was confidently changing lanes on the highway. He mastered hand-over-hand steering for precise control and learned to judge the current vehicle condition by listening to tire sounds. The most important change was the shift from tension to concentration.

* Beginner driver anxiety → understanding scientific principles → repeated training → transformation into automated driving habits
* Practical techniques immediately applicable on everyday roads, not just circuits
* Numerous testimonies of 40% reduction in lane-changing and high-speed driving time after recovering driving confidence

Q1: Is Out-In-Out cornering necessary on regular roads? Isn't it just a circuit driving technique?

A: No, it is not. Out-In-Out is not a racing technique but a fundamental principle of vehicle physics. It applies to everyday situations such as highway entrances, tollgate corners, and even turning angles on rainy days. CEO Yoon Chul-soo emphasizes that "driving without knowing this principle is the problem." The lower the speed, the easier it is to apply, so it's the most appropriate technique for beginner drivers to learn.

Q2: Do you really need to prepare for lane changes 50 meters in advance? Isn't that too far?

A: 50 meters is approximately 1.8 seconds at 100 km/h. This time is sufficient to overcome brain lag (reaction delay) and predict the vehicle's movement. Most of the tension and skidding beginner drivers experience comes from starting lane changes too late. Starting 50 meters in advance actually creates more time and allows intentional manipulation rather than reflexive action. After just a few practice attempts on actual roads, it becomes an automatic habit.

Q3: Does Out-In-Out apply on wet or snowy roads?

A: Yes, it's even more important. On wet roads, tire grip decreases by 50-70%, so consistent, accurate paths and smooth manipulation are essential. The Out-In-Out principle is a technique for controlling the vehicle within the grip range available to the tires, so this technique is especially accident-preventive in bad weather. Yoon Chul-soo Driving Academy's safety education program particularly emphasizes applying Out-In-Out in adverse weather conditions.

The tension you feel when getting on a highway for the first time after getting your license, the feeling of your car swaying when turning a corner, the fear of the steering wheel sliding on wet roads — all of this is not due to insufficient driving skill but because you don't know the correct principle.

The Out-In-Out cornering presented by Yoon Chul-soo Driving Academy is a technique that transforms this anxiety into scientific understanding. By following the five-step systematic process, even beginner drivers can immediately perform lane changes stably on real roads. When your line of sight, deceleration timing, and precise steering all align perfectly, driving is no longer something to fear but a pleasure of control.

The first step in graduating from beginner driver status lies in developing correct driving habits. Based on approximately 40 years of racing circuit experience accumulated in Jung-gu, Seoul, YCS Motorsports Group under CEO Yoon Chul-soo and President Shim Jae-woo provides comprehensive education that goes beyond simple driving instruction to encompass vehicle physics and safety principles.
