I don't think we're going to see any progress until everyone accepts openly that encouraging cycling and restricting driving in one area must be balanced by the opposite in another.
For example, the QBC should have been shorter, perhaps two or three blocks long and painted entirely as a bike lane. Within that there should have been no parking at all. Although motor vehicles would still be able to use it, there should have been priority at all times for cyclists.
The streets parallel to the east and west should then have no bike lanes and cyclists encouraged to use the QBC.
As a first principle I would suggest thinking of adaptations to the streets that spread some of the fear currently felt by cyclists onto drivers. How would you do that? I don't know but I think it's a rich vein to mine.
