I have a bell but tend to forget it's there. By the time I remember it is and reach for the trigger, the moment has passed. I'm the same way with a motorcycle horn. Some of this is due to the fact that you steer a bicycle or motorcycle with your fingers and toes while you control a car with your arms and legs. Whoever invented the car horn and then made the button ten inches wide across the middle of the steering wheel was either a genius or history's greatest monster.
