I can never understand just what use a horn is. I drive using both hands and both feet. If I see something ahead which might cause me to change my direction and/or speed then I'm far too busy to use the horn because I'm covering the indicator in case I have to pull out, covering the brake and clutch because I might need to change speed and checking the mirrors. Just what do I have spare to use on the horn? 
I've only been driving for thirty years and the only time I ever hear the horn on my car is when it goes in for it's MOT
