For this straight segment, you should maintain full throttle throughout. Keep the car in 3rd gear, and aim to carry as much speed as possible through this section. Focus on a smooth, consistent throttle application to maximize your exit speed onto the next corner. Remember, the key for a straight is to maintain momentum - avoid any unnecessary braking or throttle lifts. Stay committed to the throttle and let the car build up speed. This will set you up well for the upcoming corner.
