I didnt even think of that, but it is soo true. Going from the ferry to bay bridge tunnel is literally the easiest driving of that whole trip, one or two roads south, if your heading south your good. But after the baybridge tunnel (stop midway for your swig of free no name soda) it gets pretty gnarly real fast. I've done it over a dozen times each time its different. They like switch roads and signs every six weeks just to F with people I swear. Dont use google maps for that, physically bring a map with you and know the roads before you get there, if you dont oh well you should probably just pull over and off yourself.
