A student bоrrоwed her rоommаte’s cаr to pick up а pizza that they had ordered. On the way and without permission from the roommate, the student drove the car to a bookstore approximately two miles from the pizzeria and spent ten minutes in the store finding and purchasing a book she needed for a class. She arrived at the pizzeria ten minutes after the pizza was supposed to be ready but had to wait a few more minutes for it to be done. She brought it back to the car, which she had parked on the street in a marked parallel parking space, and saw to her dismay that the car had been struck by a hit-and-run driver. There were a number of dents in the back of the car, amounting to $900 in damage. If the roommate sues the student for the damage to her car, what will she likely recover?
