Is it time to start calling out bad cyclists?

Tom, read this:

Hit them with their ignorance of the law--hard. The highest administrative court in the country has spoken. :)

Interesting. But (from reading the article), doesn't that mean they can still enforce it under conditions, where it's dangerous etc? So how will that work, how as a cyclist will I know where I can choose not to use the cycle lane, and where I have to?

At least it's a step up from mandatory cycle lanes everywhere.
