I honk on sharp blind bends. Brought up in Devon where the lanes don't give any chance of mercy. Similar ones exist in Suffolk
And in Dorset, especially on Cranborne Chase. Three years ago we took a couple of American friends for a brief tour of the Dorset byways in our tin-top. Apparently one of the ladies kept her eyes closed the whole way. Not my driving, but she'd never been out of the U.S. before and couldn't handle being on the "wrong" side of the narrow roads. Yes I did use the horn.
