You know what is going to be really funny here?   It will be when this $20+Billion monster is all done and it is crawling along at 15 mph, crammed full of tired, sweating people that have to stand up and hold on to the straps in there for 1-2 hours just to get home.  You will be looking up from your standing still, motionless car, listening to the radio about all the traffic snafu's on the jammed up parking-lot "freeway", and realize that the traffic is even worse than it was before!
It is then that everybody will realize that this thing didn't accomplish one  damn thing except put us all in debt forever.
