According to Andrew Sullivan of National Review Online, London engineers have solved its intense traffic problems with a little free-market innovation.

By setting up monitors at the entrances and exits of central traffic routes, motorists can now be charged a fee for driving at peak hours. And if you haven’t paid the fee, you pay a hefty fine. Results have been nothing short of spectacular: a return to traffic levels of the 1950s!

According to Sullivan, this eco-friendly program deserves high praise: “It’s pure market economics to achieve a good environmental result. It’s Friedmanism for a traditionally liberal cause.”
