A nice fantasy but it will never actually fly. And let's not forget that the reason the Geary corridor gets ignored is that there's no consensus among residents and businesses along Geary in favor of rail transit, especially underground rail transit.

Personally, only one thing about the idea excites me: the potential to bring long distance rail to points other than SoCal into downtown SF. Otherwise, I don't see it as better or more likely to happen than a BART or Muni Metro extension out Geary.
