Because of her low rating, Lacie can only rent an older car to drive to the wedding, which she cannot recharge when it runs out of power. She is forced to hitchhike with Susan (Cherry Jones), a truck driver with a rating of 1.4. Susan tells Lacie that she used to care about her rating until her late husband was passed over for vital cancer treatment because their scores were deemed not high enough; she says she feels much freer without obsessing over ratings.
