On the surface, this sounds like a great idea. The problem is that, once you look at the details, you realize there are none.

How is this going to work? Where does that $68bn get re-allocated? Who will benefit from this? What is the economic advantage of investing in transit infrastructure in dollars and cents?

I've seen a few of these proposals that sell hopes and dreams with no discussion of how it's going to work. Until I see that, I can't support this.
