Final answer:
The text does not explicitly state why Sammy didn't want to leave the car, but based on the context, he was likely afraid of the dark or too tired to leave and wanted to wait until morning.
Step-by-step explanation:
Based on the provided excerpts, there isn’t a direct statement addressing why Sammy didn’t want to leave the car. However, considering the overall mood of the excerpts and the nature of the situations described, it seems more likely that Sammy was afraid of the dark or he was tired and wanted to wait until morning.
These two options align more closely with the characters' experiences of discomfort in trying times. Sammy's age isn't specified, but a fear of darkness is natural for younger individuals, especially in unfamiliar or unsettling circumstances. Moreover, tiredness at the end of a long day would make anyone reluctant to leave the perceived safety of a vehicle.
Without additional context or a specific excerpt that directly answers the question, we can only infer from the general situations described in the text. Mental states like fear and exhaustion are commonly depicted reasons in literature for characters to seek the security of familiar places, such as staying in a car.
