You obviously don't live in the area or drive on the 40th street overpass. I do. I don't work for Microsoft, and I would use that road several times per month just in the course of travelling to various entertainment venues.
What we have here is a non-story about a project that is useful, estimated to cost between 15-36M, and which Microsoft has already dropped $11M on. Show me how many Seattle businesses are willing to put extra cash of their own (in addition to tax base they already supply) on the line to dig their fancy tunnel.
Oh yeah, the only people in Seattle that regularly write checks for public works are retired Microsoft employees...weird.
