If you look at cars as a capsule with 'out-of-network' capabilities, it is pretty interesting. You can whether bring local transportation on both side (start or end) of the railway-like network, where walking would not be possible (long distance, no other alternatives...).
In the video you have both experiences, public shared capsule (glassed bus) and private capsule (cars) and in that way, you can address both needs without providing too much stations/lifs and still able to bring access to big cities for people living in peripheral areas.
It's one solution that can make it, not the only one though, but it's a good point of view of future cities.
