A significant part of the problem, not mentioned in the article, is that many pothole problems stem from the buses. A few years back the standard double decker run by Lothian Buses increased in size by about a tonne. When the buses are running full, the downward force when brakes are applied, accounts for much of the gouging of potholes in the roadway at bustops.
Of course, this is not the whole story and it underlines the importance of basic maintenance rather than spending money on new initiatives.
