The one article we read talked about the physical space of the car and the ways that it can be interpreted. Think of this in terms of “Little Miss Sunshine.” There is a family instead of a young male. There is a VW Bus instead of a convertible. The car can’t shift without being pushed. These things kinda sorta go against the typical ideas of of being on the road. However, think of the metaphors you can take away from these deviations. It’s a breaking family, they are tied down by and connected to each other; hence, the closed roof and barely functioning Bus. At the end, after their journey on the road, they come together as one unit and a sense of fulfillment takes over. Basically, the representation of The Road in this movie proves how Icons can be reworked to symbolize certain meanings.
Also, I couldn’t find a good clip of them driving or pushing the car. But the movie as whole has a bunch of Road Culture representations: the diner with the friendly waitress, the semi-skeezy gas station, run in with a cop, and the desert backgrounds.
