For this straight segment, you should maintain full throttle application throughout. Focus on keeping the car stable and in the desired gear, which in this case is 4th gear. Avoid any unnecessary braking or throttle modulation, as this can disrupt the car's momentum and stability. Keep your steering inputs smooth and consistent to maintain a straight line through the segment. Remember, the key here is to carry as much speed as possible while keeping the car balanced and under control. Maintain your focus and discipline to maximize your performance through this high-speed section of the track.
