My husband takes casual carpool most mornings to SF from Berkeley, and last week got a ride in one of the Mercedes Intelligent Drive cars (he mentioned the model, but I forgot). He said the driver didn't have to handle the car at all once he was picked up. The car drove itself onto the freeway, all the way over on the Bay Bridge, navigated the exit into SF and drove several blocks in the city. He said the driver took over only at the very end, when he pulled to the side of the road to drop my husband and the other passenger off. Pretty incredible!
