In Oxford it is not an unusual occurrence to see the traffic (waiting to get through Frideswide Square with its 35 traffic lights) extend back into St Giles, thus creating a vast amount of pollution to the atmosphere.
The alternative is a six-mile detour, again creating pollution.
When constructed, common sense would have indicated a circulatory system with no right turns.
Some time ago, this folly was recognised and a proposal made to rectify, but so far this has been talk with no action.
