Very simply, I don't want people driving around New York with blown-out mufflers. I have to deal with these people all the time. They are a constant, low-level annoyance that lowers quality of life for everyone in the city. Presently, there are presently no consequences for this sort of selfish behavior, and I'd like that to change by ticketing the perpetrators.
I don't understand what the added value is in making ordinary New Yorkers call the police with a time and cross-street as a precondition for a summons. What are we gaining here? Are we trying to validate the existence of a victim? Of course there is a victim -- there is hardly a block of the city where a loud motorist will not be negatively impacting a resident's life. This place is incredibly crowded. People live almost everywhere. Are we assuming that a manual reviewer is going to be more effective than an automated system? How? At the end of the day, they're going to have to base their judgment on a decibel reading anyways.
