In New York City, "meter-maid vehicles" like this Westward GO-4 Interceptor are generally associated with the NYPD, which owns a large fleet of them, but you also occasionally spot one on the street belonging to an individual or a business. Borough Park seems to be home to a particularly high number of these privately owned three-wheeled buggies; one Hasidic guy here told me that Jews in his community often buy them from the city at government auctions.
I love the name (Westward Go-4 Interceptor) – although I struggle to see them being able to intercept anything.
