Is it time to start calling out bad cyclists?

Curiously enough having just read this I went up to Stoke Newington Church St and noticed that Edward's Lane has been made two-way for cyclists now. In essence, formalising something that has been happening for years in the way you suggest.

Yup, another useful little scheme. If they haven't already done so, the area behind Stoke Newington Town Hall should be improved as part of the same scheme. (I haven't taken a look at it yet.)

I'm pretty sure Edward's Lane would have been made one-way when there would have been a major rat-run along Edward's Lane and Queen Elizabeth's Walk (which was subsequently filtered, removing the 'need' for one-way operation, which was an anachronism).
