Lists casual car pool locations in the East Bay and San Francisco. “Casual car pools” or “ad hoc car pools” are informal car pools that form when drivers and passengers meet – without specific prior arrangement – at designated locations. There are a number of East Bay morning meeting locations, which are listed on the website. Drivers drop passengers off at Fremont and Mission Streets (or nearby) in downtown San Francisco. There is also evening return service from San Francisco to some of the East Bay locations.
