Recently drove in Scotland where built up areas generally have 20mph speed limits. I found It made little difference in overall journey time Felt safer, stopping distance much reduced Easier to join the traffic Similar speed as cyclists Felt safer and more relaxed as a pedestrian, easier to cross the road
From my experience with it being introduced in Wales, most people are happy that’s it’s implemented in their own street and area. They just hate that they also have to drive slower where other people live.
