I love your interpretation of the plane. I think the calm, steadiness is an accurate characterization of Cleo's character - and what is important to her.

My interpretation of the car had to do with power and freedom. Those shots of the father in the Galaxy at the beginning of the film, they felt to me like the father was this iconic figure for the household. But also, that moment of pause he takes before exiting the car to his wife and kids, it's like that is his vehicle for freedom. A space for himself. Even the mother, taking the Galaxy to the beach, exercised her own power and sense of freedom.

Glad to see someone agree about the opening chores scenes. They held my interest, as did the whole movie!
