A lot of negativity on here!
60 to 40 might be too big a step, but a change from 60 to 50 on a local road has greatly improved the ambience for cyclists and walkers.
One of my regular rural routes was becoming quite uncomfortable to cycle on due to volume of traffic and the fact many "law abiding" motorists drove at the NSL despite the fact this limit was set, IMO, above the safe speed for the road. Close and dangerous passes were the order of the day.
The limit was lowered to 50mph, which seems like a safe speed for the road, and the vast majority of drivers respect the limit, close and dangerous passes reduced considerably and it became much less traumatic to cycle that route.
There is still the ocasional racer on this road, but they are so few and far between as not to cause great concern.
It's time we got into line with our European neighbours where the lower limits on roads used by non -motorised modes of transport make cycling a much less stressful experience than in the UK.
