Riders are getting around town much more efficiently, benefiting from Uber's services.

I run a company called Remix, where we help about 300 cities around the world plan their transportation future, from public transit to street design.

Ride-sharing required a deep understanding of all parties involved; simply stating that cars are inefficient isn't enough to make the idea work.
