In New York City, congestion pricing leads to marked drop in pollution

I'm curious how congestion pricing became a national issue. The strength of conviction people have about this policy–almost either way, but certainly among those against–seems to scale with distance from the city.

Nobody in Idaho gets uppity about New Jersey's tolls. But they have strong, knowledge-free, almost identity-defining opinions about congestion charges.

Is it because it's a policy that's worked in Europe and Asia and is thus seen as foreign? Or because it's New York doing it, so it's branded as a tax, versus market-rate access or whatever we'd be calling it if this were done in Miami?
