Final answer:
When being passed, a motorist should maintain a steady speed and stay in their lane, avoiding sudden changes that could create a hazard. This predictable behavior is crucial for a safe passing maneuver.
Step-by-step explanation:
When a motorist is being passed by another vehicle, they should maintain a consistent speed and stay in their lane. It is important to avoid increasing speed or making any sudden maneuvers that could endanger both the overtaking and the current driver. Additionally, if one is driving at night or in reduced visibility, they should make sure their headlights are on and be extra cautious to ensure safe passing conditions. For example, if a driver like Peter, who is stuck behind a slower vehicle, decides to pass, the motorist being overtaken should not attempt to speed up or impede Peter's effort to pass. Just like an observer not wanting to alter the behavior of those being watched, the driver being passed should act predictably and not adjust their speed abruptly. Understanding the concept of relative motion, like the sidewalk and bus passenger example, is crucial for drivers. They should be aware that the overtaking vehicle will appear to move quickly past them even if they are both maintaining steady speeds.
