Years ago, private jitneys roamed up and down Mission Street collecting passengers, as an alternative to MUNI. Within the last few months, three new companies, Chariot, Leap and Loup, began offering shuttle services in San Francisco, though at least one recently suspended operations.

Host Joseph Pace looks at the politics and impacts of these upscale jitneys.
