Final answer:
The Smith System's principle of 'leaving a way out' is exemplified by driving in a position where an escape route is available, like on a multi-lane road with open space beside your vehicle.
Step-by-step explanation:
In the context of the Smith System, a good example of leaving a way out refers to the driving strategy designed to ensure that you always have an escape route while driving, to avoid collisions in case of sudden traffic changes or emergencies. For instance, when driving on a multi-lane road, it's wise to position your vehicle such that there is an open space next to you. In case the car in front of you abruptly stops, you have an available lane to move into, thus avoiding a rear-end collision. This reflects the Smith System principle of maintaining a safe stopping distance and having an available space to move into, should it become necessary.
