Taxonomy of Shared Vehicle New Mobility Options

One of my pet peeves is incorrect terminology that more than occasionally appears in the media and blogosphere, about carsharing and new mobility services.   I thought it would be helpful to put together this schematic of how I see the various service models fitting together.

I've approached it from the user's point of view and divided things into scheduled or spontaneous trips.  I've mostly cited North American companies as examples but there are plenty of companies offering similar services in Europe and starting to appear in Asia.
