this is very much true, but it is still ur choice whether u honk at them. u will find that many times people will notice 2 seconds later and give a lil thank/apology wave ur way.
i think the best way of handling it if ur in a hurry is a super short honk, just enough to wake them up without making them feel attacked.
i dont remember many sound effects, but the testosterone imbued speaker is definitely in one of the big privately-owned rock radios in germany.
one thing that always annoyed me tho is when stations play snippets of really good music in their announcements or adverts, and then resume to playing the boring songs they played the last 3 hours.
