Green Means Go

Richard Eskow ponders a world in which we could pay to turn a red light green:

What if I'm in a hurry and want to pay, but the same is true for the guy approaching in the other direction? Will it be a competitive bidding process?  Then costs could vary dramatically depending on the wealth of the parties.  Since my regular driving route takes me through downtown Beverly Hills, I'd probably lose most of my bids, causing my driving time to go up.
