New York City is going to have a "congestion charge" -- a hefty fee for driving in south Manhattan -- to reduce traffic. It's radical in the USA, though comes 45 years after Singapore did it. It's faced political opposition for many years -- are the roads for the rich or for everybody? -- but even egalitarian Sweden did it.

Even so, NYC's version is pretty basic, and in the modern world there is the opportunity to do much more and end congestion almost entirely. I explore this in my new Forbes site article at New York's Congestion charge may bode something much more radical.
