Actually I'm glad it's not easy to "beep, beep". In the US as in Canada the horn is used when you really want to scream. In the UK, Italy and France they use it to "talk" to each other, from please, I'm going, thanks..
On the roads we need less people with anger behind the wheel, it's dangerous already.
Here in Calgary you only beep when the idiot in front fell sleep at the wheel... and only after you waited for a bit. Visitors have always told me they notice how quiet it is driving in the city with comments like "drivers never use the horn around here.. nice!". Basically is offensive to honk at someone. Of course this is local culture.
