But that isn't an ideal scenario for public transit regardless of whether somebody tries to describe it that way. Very frequent stops ("station within 5 minutes walk") mean that your journey through the subway system will take a very, very long time. Driving can easily cut that time in half.
Conversely, traffic is so bad at peak hours that taking the train is faster than driving when it comes to getting home from downtown here in Chicago, even with frequent stops (and my line stops more often than most). Biking is basically always faster than driving+parking here unless you have reserved private parking on both ends or are going clear across town (8+ miles)
