Hm. It regularly used to take my friend an hour to get from Alviso to Union City on 880, but then, she couldn't use carpool lanes. Of course, 101 is frequently evil anyhow. Can't tell ya.

237 heading towards the East Bay almost always looks like way more ass than the other direction when I leave work at night, FWIW.

Oh, and allow an extra hour for rain-induced accidents...
