Final answer:
Do not take your eyes off the road for more than 2 seconds, and look ahead at least 10 seconds, which is about one city block or ¼ mile on a highway. This is critical for driving safety and reaction time.
Step-by-step explanation:
When driving, you should not take your eyes off the road for more than 2 seconds. It is also recommended that you look ahead at least 10 seconds, which typically equates to about one city block in the city and about a ¼ mile on the highway. This guideline helps ensure that you have enough time to react to any potential hazards that may arise while you're driving. Additionally, by scanning the road ahead, you can maintain a safe following distance and anticipate the actions of other drivers. Bridget's observation of cars taking 3 seconds to travel between two poles 50 meters apart pertains to the assessment of vehicle speeds and the natural application of this guideline. Being able to resolve two points, such as car headlights which are 1.3 meters apart, at a distance is also related to safety while driving and crossing the street.
