I only hit my car's horn about once a year to prevent an accident but I'd use it more if it could make one of two sounds instead of the default:

a) a gentle toot just barely louder than a conversation to egg people in front of me to put down their phones and go at the green light

b) a Union Pacific Locomotive blast that loosens fillings in people's teeth when it goes off to prevent someone from t-boning me
