It lets you put the non-car stuff closer together, so you're traveling less distance to get to the same place. It requires urban design, not just a single person switching between modes of transit.

(Although switching to cycling can often make transit both faster for you and the people around you in a city because you aren't as affected by traffic and don't create as much traffic)
