Whites Only in Oakland?

Is it just me, or does anyone else find it a bit odd that PSA at the Oakland Airport has a "white lot" bus. Non-whites are not allowed on, even if they offer to ride at the back of the bus. Maybe that's why I usually park at V.I.P. or does that stand for very special people club such as the one Dawn Whiner started in Welcome to the Dollhouse? All the same, it was very odd to witness an African American driver screaming at a Korean woman. "No, no. White lot. White only. Wait for the red bus!"
