Totally random question, not really having anything to do with SFO, though I do try to take 280 over 101 if I leave SFO and travel anywhere west-bay area...

Anyway, does 280, between Saratoga Ave or CA-82 or so and I-380, that stretch of I-280, does it sport Carpool/High Occupancy (HOV) lanes? You know, those diamond lanes?

Just wondering, I have to drive into the city tomorrow and believe, for the most part, 280 is the better way to go over 101 but because a few of us are in the car, 101 (which defenitely sports carpool lanes) might be a better bet?

Anyway, a little random advice would be appreciated! Thanks!
