Is it faster to take the subway or drive a car?
Sometimes it is faster to take the subway and sometimes it is faster to drive a car. The answer for any particular trip primarily depends on the origin and destination of the trip. If the origin and destination are both near a subway station, then it is often faster to take the subway, especially if there is a lot of automobile traffic on the roads and you do not need to connect between subway lines. But if either the origin or destination, or both, are far from a subway station, then the total time for the trip may be dominated by the time it takes to get to and from the subway station on either or both ends of the journey; this may add enough time to the time spent on the subway so that the total trip end-to-end takes longer than driving the whole way.
