"I recently moved from San Francisco to Oakland which has had some impact on my commute. Rather than waiting for a sporadic public bus across town to campus, I instead stroll two blocks to catch a Casual Carpool ('CCP') ride. During commute hours, those seeking a ride to San Francisco arrive at the CCP stop on foot, while those with space in their cars come looking for riders. At my particular location, there is usually a line of cars waiting for passengers. When it is your turn, you hop into the first car in the queue, and off you go. By convention, the driver drops of his/her passengers at a standard location in downtown San Francisco. Barring a major accident, this takes about 15 minutes, substantially less time than driving on your own."
