Taxis are not the preferred mode of transportation in The Big Lebowski. That would be The Dude's 1972 Pontiac LeBaron: "green, with some rust coloration." (See here for discussion of what model the car actually is.) Of course there is one very memorable taxi scene after Lebowski's expulsion from Jackie Treehorn's garden party and the nice quiet beach community of Malibu. Needless to say The Dude's head injury does not affect his musical taste. Is it too much to ask for a little Creedence?
