Track features are the various components that make up a track, such as the lanes, curves, and straights. The lanes are the most important part of a track, as they determine the direction of the race and the number of competitors that can participate. The curves and straights provide the challenge and excitement of the race, while the other features, such as the starting line, finish line, and pit stops, provide the necessary structure for the race. Track features also include safety features, such as guard rails and barriers, which help to protect drivers and spectators from harm.
