Make ride-sharing fast, easy and cheap
Let's push the taxi companies to follow closely and pair up with local entrepreneurs to learn about "social transit" as being piloted in New York City right now by the company Weeels (http://www.weeels.org/) for easier and simpler taxi sharing. The Vancouver fleet is already on hybrids, and this will further help taxis be more efficient in their use of roadspace as well!
Translink has a monopoly on transit. If it did not, anyone could pickup passengers for a fare.
