If you're in the Bay Area, you can add Lyft's upcoming carpooling service to the list of ridesharing options you can use to get around. The company has joined forces with the Metropolitan Transportation Commission (MTC) and SF Bay's 511 Rideshare program to launch a new carpooling service separate from its other products. Based on the info available on its website, it'll work just like any other similar offering: simply tell the app your route, and it will match you with people going the same way. You save money, and so will they.
