You drive defensively when you:

Driving defensively means being aware of your surroundings and anticipating potential hazards on the road. When you keep your eyes moving to look for possible hazards, you are actively scanning for anything that could pose a danger, such as pedestrians, cyclists, other vehicles, road conditions, and traffic signs. This proactive approach allows you to react quickly and make informed driving decisions, enhancing your safety and the safety of others on the road.

In contrast, keeping your eyes fixed straight ahead could lead to missing important cues, such as a car braking unexpectedly or a child running into the road. Focusing only on the vehicles in front of you restricts your field of vision and could result in being unprepared for hazards that may arise from the sides or behind. Maintaining a constant speed regardless of traffic conditions does not account for the need to adjust your driving based on the behavior of other road users, which is essential in defensive driving.
