There is little doubt that one of the greatest achievements in the history of transport is the car horn. Invented in 1883 by Dr Frank Horn, three years before the invention on the motor car, the car horn represents our simplest and most direct form of communication, allowing drivers to sound warnings, vent frustrations and even knock out the odd jaunty tune.
Nevertheless, it has long been recognised that the particular weakness of the car horn is that it is not directional and when used in heavy traffic it's not always clear who the warning is aimed at. Well now Professor Jez Moonbeam, inventor of bioluminescent cheesecake, has come up with the first narrowband car horn. The horn will be available for most vehicle makes early next year, and Moonbeam believes that it will revolutionise our driving experience. He claims that his creation creates a beam of sound that will have a positive impact on noise pollution and reduce confusion to other road users, while still being heard loudly and clearly by the bastard that just cut you up.
