Considering the controversy over how airport concessions were awarded, I would assume Reed is avoiding doing an "Atlanta-only" type of tax for transit construction. Reed is alleged to have a lot of friends in the construction business, and he has already made a comment to reporters about awarding contracts to minority businesses - instead of simply implying that the best company at the best price quoted would get these jobs, as it should be. Some folks are having a deja vu where the name "Bill Campbell" pops into their head - they do not want a repeat of that. There is simply A LOT of mistrust in both regional, State, and local government today as was reflected in the recent vote. I think a lot of good behavior is needed first before even intown residents are willing to fork over more to transit construction.
If you look at the plans for the first segment of the street cars, it's an example of horrible planning. It completely bypasses several major hotels by several blocks, and loops around Centennial Park also several walking blocks away from the Georgia Aquarium. It's not at ALL tourist friendly, and seems to only truly benefit the Auburn Avenue/MLK site. One has to wonder if this street car is really something to benefit all of Atlanta - or just the King family.
