Vancouver's congested streets can be maddening -- unless, as the blog Hugeasscity notes, you're a pedestrian or bicyclist. But will that frustration translate into momentum for policy change?
As someone passing through I typically must drive. SkyTrain is great you go where it goes but my recent trips took me to UBC or on detours between Whistler and Seattle, where there aren't feasible transit options. The vast majority of Lower Mainland residents are the in the same situation until land use policy puts more housing within striking distance of transit (or walking or biking).
Vancouver's clogged street grid doesn't necessarily make the case for congestion pricing, at least off the downtown peninsula. Seattle's hills and water are a much better testing ground for combining a) alternative forms of travel with b) tolling that varies with usage. If the goal is to use congestion pricing to make more efficient use of finite resources, Seattle would be a great place to start.
