Its comparing your body to the car, if you take care of it you should take care of yourself.
Your food to gas
Your organs to the parts in a car
Your pride for your body to the pride of your car
In two different settings, there may be different trials to be faced or different rules. Depending on where the character is will affect the way they act. For example, if a character was at a fancy restaurant they may act differently than they might've if they were at a crime scene. I hope this is helpful!!
