Many cheap car FM transmitters default to that frequency, but that doesn't explain why you were hearing a doctor's receptionist. They are normally used to transmit MP3 music files from an SD card or pendrive, or to relay music from a phone via Bluetooth. I guess someone may have left a phone connected to BT while phoning the doctor from the car park.
