early Western films in the United States, road movies were later used to show how national identities were changing, such as which Edgar G. Ulmer’s Detour (1945), a film noir about a musician travelling from New York City to Hollywood who sees a nation absorbed by greed, or Dennis Hopper’s Easy Rider, which showed how American society was transformed by the social and cultural trends of the late 1960s. The New Hollywood era films made use of the new film technologies in the road movie genre, such as "fast film stock" and lightweight cameras, as well as incorporating filmmaking approaches from European cinema, such as "elliptical narrative structure and self-reflexive devices, elusive development of alienated characters; bold traveling shots and montage sequences. Road movies have been called a post-WW II genre, as they track key post-war cultural trends, such as the breakup of the traditional family structure, in which male roles were destabilized; there is focus on menacing events which impact the characters who are on the move; there is an association between the character and the mode of transportation being used (e.g., a car or motorcycle), with the car symbolizing the self in the modern culture; and there is usually a focus on men, with women typically being excluded, creating a "male escapist fantasy linking masculinity to technology". Despite these examples of the post-WW II aspects of road movies, Cohan and Hark argue that road movies go back to the 1930s.

The British Film Institute highlights ten post-2000 road films that show that "[t]here’s still plenty of gas left in the road movie genre". The BFI's top 10 include Andrea Arnold’s American Honey (2016), which used "mostly non-professional actors"; Alfonso Cuarón's Y tu mamá también (2001), about Mexican teens on the road; The Brown Bunny (2003), which garnered publicity for its "infamous fellatio scene"; Walter Salles' The Motorcycle Diaries (2004), about Che Guevera's epic motorcycle trip; Mark Duplass and Jay Duplass' The Puffy Chair (2005), the "first mumblecore road movie"; Broken Flowers (2005); Jonathan Dayton and Valerie Faris' Little Miss Sunshine (2006), about a family's trip in a VW camper van; Old Joy (2006); Alexander Payne's Nebraska
