In the last few months, Gov. Kathy Hochul has privately exchanged anxieties about moving forward on congestion pricing with business leaders, political advisers and, in her telling, a great number of ordinary New Yorkers in diners.

But she never shared them with the group that would be most affected by the program: the public at large, which had every reason to believe that the new tolling structure would be in place in Manhattan later this month.

The move to abandon a plan that was decades in the making jolted lawmakers, real estate leaders, transit advocates and other stakeholders. The governor said she was reluctant to deter people from driving to New York City when its economic recovery was still fragile; critics called it an election year ploy to help Democrats in suburban districts where congestion pricing is notably unpopular.

Ms. Hochul’s announcement was particularly jarring given her past championing of the plan. Indeed, as recently as this year, the governor stressed the need to get vehicles off the road — a dissonance that has fed a sense of duplicity and a feeling of betrayal among those who considered her an ally.

On Friday, Jon Orcutt, a longtime congestion pricing proponent and a consultant for Reinvent Albany, described Ms. Hochul’s about-face as “a fundamental sense of betrayal, like, inner-core rock bottom.”

“It would be one thing if she inherited the thing and said, ‘This isn’t my priority,’” he added. “But we got to, not the 11th hour, but 10 seconds before midnight.”
