The mayors listed are not however making their cities particularly more accessible to pedestrians and bicyclists. They generally sandbag those improvements on the slightest complaints about loss of parking or access. DiBlasio drives to a gym in Brooklyn everyday and has the NYPD run a war on ebikes/bikes, Durkan just canceled a long-planned bike lane on an important arterial, Portland's doing a massive freeway expansion. Most of these cities are failing on Vision Zero efforts.
The reason congestion pricing is catching on is that the wealthy & politically connected older generations finally settled on it as the way to reclaim their privilege to drive straight into the downtown from their suburbs. Congestion pricing is now just another way to maintain a vehicular status quo.
