USA - The 'honk' or locally known as a 'hoot', has many benefits - it serves as a way to alert road users and pedestrians warns of dangers. Some however use it as an audible way to vent their frustrations on the road.
Using your hooter, even with the best intentions, can upset other motorists.
The courtesy honk
In a bid to change all that, YouTuber Mark Rober installed what he calls 'the courtesy honk' into his vehicle. His custom hooter has three different sounds to choose from based on a sophisticated chip that enables Rober to chop and change sound bytes.
The courtesy honk in particular creates a more friendlier sound, with two rapid, yet subtle beeps, designed to alert drivers and pedestrians in a respectful manner.
Rober jokes: 'This horn is so courteous my car was granted Canadian citizenship yesterday.'
Different honks for different times
He said: "I customized my car horn to play three different sounds. The main sound is the "Courtesy Honk" which is used to get the attention of other drivers in a non-emergency scenario. It's two quick chirps of the horn that is not only friendly sounding, but it's not as loud as a normal car horn."
