Apologies for going back on topic after all the entertaining side-tracks, to which I've contributed, had two visits to Cardiff this week, and the vibe seemed to be everyone driving at 20(ish) and everything running smoothly. I think I had one bloke up my arse wanting to put a
move on but only one out of dozens of other motorists who seemed cool with it. On the other hand a couple of conversations suggested it would greatly delay their jobs (multiple short trips in town looking after old people, my Dad for instance). My two (anecdotal) experiences suggest to me that smoothing out traffic speed helps keep traffic
moving and that the average speed is likely not much slower.
Doesn't seem a bad thing overall
