Like I said, it depends on density. If the home-to-station time is short enough then it already exists (like in New York) but in other places it's faster to just drive to the location rather than to/from a station on both ends (like in Los Angeles). Density and last mile is the critical factor. Most cities in the US are too spread out currently.
