Sometimes I have been warned by a horn and have warned others.
And as for dreamy drivers not moving when s filter at the lights say they can.. yes. Just beeps not blasts.
I hate the sound of horns blasted in anger it raises the blood pressure for everyone and is dangerous, I always doubly, triply check it isn’t me, causing the offence, no way, then hate them. It’s a scary aggressive tactic.
And while we are at it people who don’t acknowledge your generosity, letting them in etc really **sses me off. (And most often round here it is young women who think they are thus entitled.
