Car horns are weirdly aggressive, so this guy made a friendlier version
16 June 2017 - Mashable
Driving can already be stressful enough, and it's not helped by the plethora of aggressive-sounding horns standard in most cars.
Fortunately, YouTuber Mark Rober has come up with the "nicest car horn ever," a higher-pitched honk that toots twice quickly.
It's for situations where you want to show courtesy, like if a driver forgets something on their roof, or you want a car to move forward in the drive-thru.
But for more pressing situations, there's a horn that bellows like an ocean liner — perfect when you want to warn some pesky kids off the road. Car makers, it's not a bad idea.
