IF congestion at the M60-A56 junction is caused by too many traffic lights and a badly-placed pedestrian crossing, as a recent correspondent suggested, what might be the cause of congestion on a four-lane motorway?

Driving too fast, too close, too erratically; being too impatient and too inconsiderate; too much acceleration and braking, and too many collisions. Isn't there one nearly every day on the M60? Too many lights, yes - but brake lights, not traffic lights.

The most cost-effective way to ease congestion and pollution would be speed reduction: 56mph on the M60 and 20mph through Prestwich village, with tailgating, intimidation and erratic lane-changing being a serious offence.

Remove the "speed freaks" and "speed merchants" from the system and traffic flow will be smoother and quicker. It isn't rocket science, is it?
