When matt “borrowed” his mom’s car, he couldn’t go home because he would be caught. he soon realized that the vehicle itself was a jail cell. this example uses a metaphor because question 9 options: it compares all cars to jail cells. once you start driving, you can't stop. it compares matt's mother to a prison guard because he knows she will call the police. it compares matt's mom's car (that he shouldn't be driving) to a jail cell. it shows that he feels trapped in a bad situation. it compares the house to a prison that he must escape.
