Curbing City Drivers

"The city of London launched a bold experiment last week to nudge drivers of private cars onto public transport. It started charging drivers $8 a day to enter the city center during weekdays. So far, it's working well. Traffic congestion is down about 20 percent. Pollution is less, pedestrians are safer, and the city will have more money to improve railways. The system works by having hundreds of cameras read the license plates of cars entering the city. Computers then check the numbers against a list of people who have paid the fee."
