Why is it necessary to adjust the distance from the vehicle ahead in city driving?

Adjusting the distance from the vehicle ahead in city driving is essential primarily to avoid sudden stops. In urban environments, traffic patterns can be unpredictable due to frequent stops for signals, turns, and pedestrians. By maintaining a safe following distance, a driver can react appropriately to sudden changes in speed, reducing the risk of rear-end collisions. This buffer allows ample time to brake gradually rather than slamming on the brakes, which not only enhances safety but also contributes to a smoother driving experience.

While considerations like avoiding distractions, ensuring visibility, and allowing room for lane changes are important aspects of driving, the primary focus during city driving should be on maintaining the appropriate following distance to handle the stop-and-go nature of urban traffic effectively.
