I hear about visitors to the city parking their cars at far out train stations like Stamford and Metropark and taking the commuter trains in. A car just gets in the way in the city.
Oh, and would the powerful tourism industry be interested in my proposal to build a streetcar line on Grand Street. It's close enough to Canal street, falls neatly on the south of Soho and the north of Chinatown, and goes to the subway-less lower east side.
