Horns have always been a very important part of a car. They were invented to warn drivers of other drivers on the road. Horns were also invented to assist the middle finger in descriptive impromptu editorials that register drivers’ displeasure with other drivers on the road, and to engage in general non-verbal communication with other traffic participants.. History does not appear to have recorded the chicken/egg side of the equation which would sort out which came first in the automobile horn/middle finger debate.
Car horns have saved lives and cost teeth, depending upon the traffic circumstances and emotional control of drivers. An errant car horn can be an instant turbo-boost to uncontrollable road rage under the right conditions, but we still love them. Let’s see how much we do.
