75 percent of the people that sell out ATT every game are from the south & east bay, if the post game traffic on hwys 80 and 101 are any indication.
The ballgames usually end right around the rush hour. That's just the way the games go when they start at 1:00 P.M.
I can recall a July 4th doubleheader that was on a Saturday, a three-day weekend and was over PRECISELY at rush hour.
It was the very WORST traffic jam the bay area had EVER seen. Really bad planning. With all the bays and bridges there is NOWHERE to go but right in back of the eight zillion cars in front of you.
