Driven to radicalism.

The article looks at discussion surrounding the implementation of a national road-pricing scheme in England. Transportation and politics do not mix. Road and rail policy operates on time-spans of a decade or more, offering little electoral advantage to ministers, who are never more than five years away from losing their jobs. So it was nice to see Alistair Darling, the transport secretary, taking the long view last week by restarting the debate on using pricing to reduce congestion on Britain's worsening roads. Everyone agrees that big changes are needed. The problem is not a lack of capacity (most roads are empty most of the time) but the lack of an efficient system for allocating it. A system that charged individual drivers for the costs of increased traffic density, vehicle emissions and damage to the roads would encourage more efficient use of a scarce resource and be fairer to boot.
