Use of the car horn

I often find myself reflecting on what ought to be an improvement to the caveman-esque communication method, which is the car horn.

My theory generally goes that the vast majority of use of a car horn, in the UK at least, is not for its intended of use of signalling to others to watch out. Instead it probably has most use in telling people they're idiots, perhaps for pulling out in front of you. Next, letting the person in front know that the light has turned green, followed by letting your friends know you're waiting outside or just leaving. And, lastly, to let people know to watch out.

But it’s harder than it seems, I'd guess, to make something that supports helpful behaviour provides safety and avoids lawsuits. Surely can’t be that hard though…
