You drive on in silence with tension between you and the girl. You cannot figure her out. You have offered her help and know she is curious about why you are here. You have business just as she does and not everyone needs to know. You do not want to trust her but you need her to tell her where you are going. You hate these situations where you have to depend on others. Finally a light in the distance. Relief.
You:
Decide you do not need her help any longer
Decide to take her to the motel and then leave her
Are impressed and offer to drop her wherever she pleases
