Final answer:
The final step in lane changing is to ensure there is sufficient open space around the vehicle, considering the dimensions and speeds of surrounding vehicles.
Step-by-step explanation:
The final step in lane changing is to ensure there is adequate separation or open space around the vehicle. This involves checking for sufficient space to the front, rear, and sides of your vehicle. When changing lanes, the driver must be aware of the dimensions and speeds of surrounding vehicles, much like the scenario of crossing a road safely where one must travel further than the width of an approaching car.
In conditions like those described for a city such as New York, where paths are zigzagged, the importance of open space and directional movement is emphasized to prevent collisions. Similarly, creating separation during lane changes allows for a safer driving environment, mitigating risks associated with close proximity to other vehicles or unexpected hindrances.
To effectively gauge this separation, one can consider the speed limits in urban areas and the average lengths and widths of vehicles. Knowing these measurements helps in determining safe distances for lane changes or crossing the road. For instance, being able to walk 4 meters in total before a car reaches you - taking into account the car's width and an additional margin - serves as a guideline for safety.
