Maybe it's the cost of the cameras to be installed.
It's not. 85% of Manhattan households don't own a car at all. The number is even higher inside the Congestion and Relief Zone. Almost all car traffic within the zone is from people who do not live within the zone.
There's no real way to get reliable numbers on this, but I would estimate that >70% of people who live in the Congestion Relief Zone and own a car use it primarily as a way to access their second home in the Hudson Valley.
I would have said that in 2019, but the testimony from congestion pricing opponents during the multiple rounds of public hearings that we've had since then only further corroborate that impression.
It's like all the efforts to drug test people on welfare, they cost vastly more than they save/recover.
