Absolutely. But there will always be people who want to get to locations spread all around even a metropolitan area (as well as further-flung locations around that area), and while it's possible to build a public transit network to get them there, with enough throughput to cover the volume of people, the latency will still be worse than a point-to-point trip directly from point A to point B.
