"On balance I still think a >=5mph reduction in 50% of vehicles at the cost of a little signage is quite a win"
Thats what I was getting at yesterday - its (far from) perfect, but it is an improvement on before - not just IMO, but I know 2 cycling families who live on West Saville, and they say exactly the same as Dave.
Big Q's -
Would we (in 20 mph zones) rather have it back to 30? Answer from me - no.
Do we think it can be even better? Answer from me - yes.
