I remember what I was a teenager (yes, that was a few years ago) working in my father's service station. The latest safety gadget in new vehicles was a buzzer that warned the driver when seatbelts were not fastened. That's a good idea, right? Apparently not as customers were coming in to see if they could have the buzzer removed or disabled. If everyone got in, fastened their seatbelts and then the driver started the car, no one ever heard the buzzer. I suppose the trouble was that this was not the habit and it was easier to silence the buzzer than it was to change behaviour.
