"Cars Hiss by My Window" is a slow blues composition written by Jim Morrison for The Doors' sixth and final studio album with Morrison, L.A. Woman, released in 1971. The song grew out of informal blues improvisations during the album sessions in December 1970, when the band devoted a day to working through blues-oriented material. Morrison drew lyrical inspiration from his experiences in a sweltering Venice Beach apartment, where the sound of passing traffic through an open window merged with the ambient heat and emotional tension of the moment. The title's onomatopoeic quality captures that nocturnal atmosphere, with the hiss of cars likened to ocean waves. Musically, the composition follows a straightforward three-chord blues progression in the tradition of Jimmy Reed, whose influence Morrison openly acknowledged. The band even used the working title "The Bastard Son of Jimmy and Mama Reed" during sessions. A languid, mournful guitar riff anchors the piece, while brushwork on drums creates a muffled, intimate texture that complements Morrison's deep, weary vocal delivery. The song occupies a distinctive place on L.A. Woman as one of its most stripped-down and introspective tracks, trading the album's characteristic blues-rock energy for a subdued, almost nocturnal stillness rooted in Chicago blues tradition.
