Why is it dangerous to follow the same vehicle for a long time on an interstate?

Following the same vehicle for an extended period on an interstate can lead to a false sense of security and complacency, where a driver may become overly relaxed and lose concentration. This mental state can significantly diminish the driver’s alertness to changing road conditions, potential hazards, or the behavior of other drivers.

Long stretches of following another vehicle can also create a monotonous driving experience, which might cause daydreaming or a lapse in focus on the road. It’s vital for drivers to stay engaged and attentive at all times, as even a momentary distraction can lead to dangerous situations, especially in a high-speed environment like an interstate. Regularly changing the focus of attention—by scanning the environment and being aware of surroundings—enhances overall driving safety.
