London's congestion charge worked: don't scrap it now

"Put simply, in order to cope with more people travelling in central London, the car had to be displaced and dethroned as king of the road. It was not a Charles Ist-style execution, but more a piecemeal easing aside in that more modern English tradition of change... The big success of the congestion charge is that it created space for bus lanes, cycling facilities and pedestrian priority." (Source: The Guardian)
