Final answer:
Using the shoulder, breakdown lane, or sidewalk for passing is not safe or legal. These areas are intended for different uses such as emergencies or pedestrian movement. Observers may perceive the speed of moving objects differently based on their frame of reference.
Step-by-step explanation:
The shoulder of a road, breakdown lane, or sidewalk are not proper places for passing another vehicle. Passing should always be done in designated passing zones within the roadway lanes and according to traffic rules. Using the shoulder for passing is dangerous and illegal as it is intended for emergency stops and breakdowns, not for vehicular traffic. Similarly, the sidewalk is exclusively for pedestrian use. Drivers should always ensure they are passing safely and legally within the correct lanes and at the proper speed limit.
Regarding safety, crossing the road outside a designated pedestrian crossing can be hazardous. Therefore, proper judgment is needed to determine when it might be safe to cross, which usually involves gauging the distance and speed of oncoming cars. It should be noted that the color of a car does not determine the speed at which it travels, and crossing decisions should not be based on vehicle color.
Further to the dynamics of motion as observed from different viewpoints, observers may perceive speed differently depending on their frame of reference. To a bus passenger, another bus passenger may appear to be moving slowly, while to a sidewalk observer, the same person may appear to be moving more quickly due to the movement of the bus itself.
