A lot of the mid-60's through mid-70's GM had a little indicator on the speedometer that you could set to any speed to sound a buzzer. My mom called it a tattle-tale. When the speedometer's needle got up to it a buzzer would remind you to slow down. Worked great until dad got annoyed and cranked it up to 90 to shut it up.
