Yeah, there are plenty of "good" reverse commutes in the bay area still. The only problem is it only takes one chunk of "bad" road (eg, as you mention, avoid 880, or going the 'wrong' direction on any piece of road, or being near a major interchange) that not THAT many people have a truly 100% reverse commute. Ours is, and yeah, it's pretty funny to cruise at 90 while the traffic coming the other way is stopped.
