Final answer:
Center left turn lanes are designated for making left turns and should not be used as through lanes. Exceptional circumstances, such as a medical emergency, may legally allow for deviations from standard traffic laws.
Step-by-step explanation:
The proper use of center left turn lanes on roadways is essential for traffic safety and efficient vehicle flow. These lanes are designated for drivers who are making left turns, typically indicated by road markings and signs. It is crucial to enter these lanes only when preparing to make a left turn and not use them as a through lane. This helps to prevent collisions with oncoming traffic and allows for smoother turns.

During such emergencies, drivers should proceed with caution, ensure it is safe before proceeding, and be prepared to explain the necessity of their actions to law enforcement. However, local laws may vary, and it's important to be aware of specific legal allowances for emergencies.
As for the safety of the rabbit crossing the freeway, if the car in the scenario is traveling in the furthest lane from the rabbit, there is no guarantee of the rabbit's safety as it tries to cross all three lanes. Drivers should remain vigilant and watch for wildlife on roadways to avoid accidents.
Lastly, navigating through cities like New York involves following zigzagged paths along roads and sidewalks due to the layout, rather than moving in straight lines. This is illustrated by Figure 3.2, which underlines the two-dimensional nature of urban navigation.
