Where I live it's only legal to use the horn to prevent serious situations, so someone doing this could (and would) be fined by police/eventually lose their license.
Even in places where this isn't directly illegal, is it illegal to make loud noises after certain hours? If so, that could be a reason to call the police or make some kind of official complaint against the driver.
Also, have you tried talking to this person? Maybe they don't realize that its disrupting literally everyone (a lot of people forget that other people are not just NPCs).
Not me but my partner.
She was working as a research assistant in a lab for several years. She asked her boss if she could be promoted to a research associate, which was one level above her. She already been doing the job of a researcher (3 levels above her). Her boss said that they were in a hiring freeze and that it wouldn't be possible, but maybe in 2-3 YEARS she might be up for a promotion. Her boss wanted everyone to get the most they possibly could out of their current position before promotion. What my partner heard was that even if she eventually got the promotion to the next level, it might be 5-7 years after that promotion until the next promotion.
I've never seen her so angry when she came home. She immediately started applying to new jobs in a different field. She also stopped doing work above her pay grade, to which her boss actually tried to retaliate against her. Within 2 months, she moved onto a new job that is 75% WFM, pays more, has a better culture and is in a field where she can much more easily move upward.
Her former company has started layoffs.
