Subway cares are individually devoted to one advertiser. You can ride in the Delta Airline car, the Lion King car, the MTA car, your choice when you step through those open doors. However, it’s tough when you’re waiting on the platform and a car slides by that has new ads you haven’t read, but by the time the chain of cars comes to a halt, it’s 15 cars further up the platform. So you enter a car where you’ve read all the posters and hope for more legroom as compensation.
