I must finally reveal to the world my secret for the solution to help curb NYC sound pollution and hope someone out there somehow finds a way to get this done. The solution… ::drumroll:: is to track taxi cab horn usage and impose fines based on excessive horn use. I know , I know I’m a genius , stop it, please. In my ignorant mind about cars, it seems simple enough to create a device that would activate anytime the horn is pushed, record the datetime, and record the duration of the honk. You can give the taxis some sort of quota for honk time, maybe even impose a point system based on the time of day?
