Yes, I think SF desperately needs more subway, and given the choice, I would allocate resources to that (making the city healthier and more robust) than a tunnel through the city (which helps people get through the city). Presidio to Financial subway would be amazing. At some point, however, people north of the GGB need to get to SFO and while I, traveling solo, would be happy to park and ride in Marin (which I already do with the Marin Airporter) if I am a traveler who rented my car at SFO or if I am traveling with an entire family, you need the ability to drive to the airport...
