Honk!
Instead of an incredibly loud and annoying sound whenever assholes drivers honk their horns, I think horns should instead broadcast only two phrases:
1) “AHHH. You’re about to hit me! Don’t hit me! Don’t hit me!”
OR
2) *in exaggerated baby voice* “You’re not moving your car. You’re in my way! I’m going to whine about it. Waaaa! Waaaa! Why aren’t you moving? I’m so helpless and nobody loves me! I live with my parents! I’ve never had a girlfriend in my life, so I’m going to take it out on this horn! I’m so alone.”
