Interesting... I'll pull it up and see what it does. For me, there's really no alternate routes possible, 80 to Bay Bridge and across it to S.F. I always use the HOV/carpool lane anyway and if that slows down, I'll split. On really bad days, I'll be splitting entire 35-mile commute to S.F. Takes me 45-minutes instead of 2-hrs by car... on exact same road at exactly same time-frame.
