Streetcar=light rail=subway?
If you mean that LA is trying to fund a kitschy tourist streetcar, that may be true, but Los Angeles already has two light rail and three heavy rail subway lines running under its downtown. The two light rail lines also run above ground through parts of the city, and beyond, and recent added funding will push up the timetable so that the "subway to the sea" light rail will be completed within the next decade.
