20 limits are widespread in suburban London. I see them being flagrantly ignored in the early morning when traffic is low. But during the day a combination of weight of traffic and on street parking/loading acts as natural traffic calming, plus drivers who do reduce their speed makes them appear to me to be quite effective. I think they are generally a good thing.
If I've understood correctly I think I've seen similar in France.
I think the most effective system here is to have cameras; there's a 30km/h (18mph) section on a local 'A' road equivalent where it goes through a village and drivers almost always slow down because there's a speed camera about 100m beyond the sign.
It makes crossing the road by bike easier and safer because I can merge with the traffic from the cycle lane.
Of course, the fact that any fines are collected by the town helps provide an extra incentive to maintain the camera.
