In addition to the other comments, a lot of people also drive (or get dropped off) at commuter rail stations. And, in many cases, they take transit upon arrival in the city to get to their destination. So commuter rail is really a modified point-to-point for most people in the US.<p>Commuter rail also usually doesn&#x27;t work for suburban-to-suburban commutes. It&#x27;s almost entirely a hub and spoke model with the hub being an urban core.
