[rebootthesystem]

The point you should be agreeing with is that regardless of how you build it --dig a tunnel, rip-up the sidewalk or go vertical-- the cost of such a system defies a comparison to a simple fleet of buses by a huge margin. I would venture to say one, if not two orders of magnitude.

I mean, the thing is ridiculous to such a degree that it is surprising to see anyone arguing in favor of it.

Buying a fleet of electric buses would make far more sense than this insanely ridiculous idea.
