Traveling through major U.S. cities often raises the question of whether a car is necessary. In many urban hubs, strong public transit systems eliminate the need for rentals, making it easier for visitors to explore without the stress of traffic or parking. According to the American Public Transportation Association, millions of daily commuters rely on trains, buses, and subways that are efficient and affordable. In addition to being convenient, these systems lower emissions, which promotes sustainability. Here are eight U.S. cities where public transit makes renting a car unnecessary.
1. New York City
New York City has one of the most extensive public transportation networks in the world, with the Metropolitan Transportation Authority running 24/7 subway and bus services. According to the MTA, over three million riders use the subway on an average weekday, making it the backbone of the city’s mobility. For visitors, the ease of accessing iconic attractions like Times Square or Central Park without a car highlights its efficiency. The addition of commuter trains such as the Long Island Rail Road ensures smooth travel across boroughs and beyond.

Boston’s Massachusetts Bay Transportation Authority, or the “T,” provides subway, bus, commuter rail, and ferry services across the Greater Boston area. According to the MBTA, over 1.2 million trips are taken on weekdays, demonstrating the system’s accessibility and reliability.
