A "📼🚗" is a tape cartridge designed to be used in a car audio system. It contains magnetic tape that stores audio recordings, allowing users to play music or other audio content in their vehicles. The tape cartridge is inserted into the car's cassette player, and the audio is played through the car's speakers. This technology was popular in the past but has been largely replaced by more modern formats such as CDs, MP3s, and streaming services.
