In the 1950s, "hot rodders" were a subculture of young people in the United States who were passionate about cars and racing. They were known for modifying their vehicles to make them faster and more powerful, and for participating in illegal street races. The hot rodder culture was popularized through films such as "Rebel Without a Cause" and "American Graffiti". While hot rodding was often associated with rebellion and delinquency, it also fostered a sense of community and camaraderie among enthusiasts.
