Peer-to-peer ridesharing

Peer-to-peer ridesharing can be divided along the spectrum from commercial, for-fee transportation network companies (TNC) to for-profit ridesharing services to informal nonprofit peer-to-peer carpooling arrangements. The term transportation network company comes from a 2013 California Public Utilities Commission ruling that decided to make the TNC revenue model legal.

Essentially all modern peer-to-peer ridesharing schemes rely on web application and mobile app technology.
