I concur but one of the goals of California HSR is to improve the transit systems in its host cities (Caltrain electrification and extension, Metrolink improvements, etc.) so there's reason to be optimistic, especially since the plans call for an extensive remodel of the Millbrae station.

Thinking about it more, what really boggles my mind is why BART was extended to SFO rather than extending the AirTrain to Millbrae, a la the JFK AirTrain to Jamaica. AirTrain would be perfect for the low-capacity line, cheaper to build than heavy rail, and guarantee a two-seat ride to any terminal from BART/Caltrain. I guess not that many people take Caltrain to the airport . . .
