Yeah, you can imagine it as a continuum: as you go from left to right, you have lower convenience (how far out of your route or schedule it takes you), longer trips, and lower costs, and vice versa.
On the left end would be a private, dedicated chauffer. (Or private helicopter for extreme left!) On the right end would be public transit or walking.
Putting transit options on the continuum would look like:
Private Chauffer -- Personal Car -- Taxi -- Livery/Lyft/Uber -- Lyft Line/UberPool -- Lyft Line + Hotspots -- <potential new bus-like offerings> -- public transit -- walking
