Awesome, this is exactly what I was looking for. Thank you.

There’s at least three types of horn usage:

Beep: hi, I’m right here, just a friendly reminder

Beep beep: hi or thank you or go ahead, etc. very common and generally positive intent.

Beeeeeeeeeeeeeeeeeeeeeeeeeeeeep: Jesus fucking Christ what is your fucking problem who the fuck drives like that you fuckin idiot.

Truly a beep for every occasion
