"Cars" is a 1979 song by Gary Numan, released as a single from the album The Pleasure Principle. It reached the top of the charts in several countries and today is considered a New Wave staple. In the United States, it reached #10 on the Billboard charts in 1980. However, its popularity was so enormous that it overshadowed much of the rest of Numan's career in the 1980s, causing him to be thought of in later years as a one-hit wonder in many countries.

The song was the first release credited solely to Gary Numan after he dropped the band name Tubeway Army, with which he had released four singles and two LPs, including the number one hit "Are 'Friends' Electric?", and its parent album, Replicas. Musically the new song was somewhat lighter and more pop-oriented than its predecessors, Numan later conceding that he had chart success in mind: "This was the first time I had written a song with the intention of 'maybe it could be a hit single'; I was writing this before "Are 'Friends' Electric?" happened".
