The term 'Standard Car Feature' refers to the features that are typically found in most cars. These features include a STEREO, RADIO, AM/FM STEREO, and parking brake. A STEREO is an audio system that can play music from various sources such as CDs, tapes, and digital files. A RADIO is a device that receives RADIO signals and broadcasts them as sound. An AM/FM STEREO is a combination of an AM and FM RADIO, allowing for both types of RADIO signals to be received. Finally, a parking brake is a mechanism used to keep a car stationary when it is parked.
