A bit more reaction in the Guardian to this story here.
Actually, I encountered a similar cycle lane arrangement when I was driving "up north" (I think it was through Lancaster) a few weeks ago. The cycle lane was wider than the car lane, and in fact the car lane wasn't wide enough for a car. As a driver I found it a little confusing, but that was because I'd never encountered such an arrangement before. It gives a strong message about who has priority.
