Plot Summary:Mr. Carpool (Oscar Isaac) wanders around the freeways of Los Angeles, making ends meet by offering his services as an extra passenger so they can drive in the carpooling lane. Throughout his adventures, he meets a series of oddballs, from a protein shake-pounding muscleman (Firas Al Khazaali), to high-strung business types (Charley Rossman), to a multi-tasking muncher (Michael Q. Schmidt) who drives with his hands on a burger instead of the steering wheel. While he witnesses some nervous breakdowns, high points in his day include smoking up with a relaxed truck driver (Max Minghella), getting to man the wheel while a lady gets changed for work (Kristina Korsholm), and forging a serious bond with one of his clients. This is all accompanied by Trentemøller's "Gravity," which serves to support the life-lesson with its steady pace and unobtrusive vocals.
