Uber, Lyft announce new carpooling services

SAN FRANCISCO (KGO) -- On-demand ride companies Uber, Lyft, and Sidecar already match drivers with passengers. Now they want to match passengers with other passengers.

The rival companies each announced a new carpooling service that will pair up riders who are going the same way. The strangers then split the fare.

The companies have been testing the services with a few riders before rolling out to the general public.
