Re: Well come to Norwich then...
"Over here (Basel, Switzerland) there are lots of one way streets that are open in both directions to cyclists. They work pretty well, no idea why they don't try it in the UK."
There are quite a few of those in the City of London (the financial district). Not sure if there are in other parts of the city (lower-case "c").
They are not bad except that pedestrians are never ready for a cyclist coming the "wrong" way.
